A force of 6.00 N acts in the positive direction on a 3.00 kg object, originally traveling at +15.0 m/s, for 10.0 s. (a) What is the object’s change in momentum?
Answer:
60 kg m/s
Explanation:
F= Force = 6 N
m = Mass of object = 3 kg
u = Initial velocity = 15 m/s
t = Time = 10 s
v = Final velocity
[tex]\Delta p[/tex] = Change in momentum
Force is given by
[tex]F=\dfrac{\Delta p}{t}\\\Rightarrow Ft=\Delta p\\\Rightarrow \Delta p=6\times 10\\\Rightarrow \Delta p=60\ \text{Ns}[/tex]
The change in momentum of the object is 60 kg m/s.

A video game where characters fight on different platforms needs to constantly update the speed and position of the characters. Which measure would be an initial condition in one of these games?
the size of the character in pixels
the downward acceleration due to gravity
the designation of y=0 as the lowest platform
the speed of a character at the moment of contact
Answer:
d: the speed of a character at the moment of contact
Explanation:
did the quick check
The measure which would be an initial condition in one of these games is
speed of a character at the moment of contact.
The speed of the character at the point of contact is the most suitable
option which tells the exact speed and position of the character in the
video game.
The moment of contact will determine the type of movement and position
exhibited by the players which can then be immediately updated when the
game is being played.

A 55-kg woman is wearing high heels. If each heel has a circular cross-section 6.0 mm in diameter and she puts all her weight on one heel, how much pressure does that exert on the floor
Answer:
The pressure exerted by the woman on the floor is 1.9061 x 10⁷ N/m²
Explanation:
Given;
mass of the woman, m = 55 kg
diameter of the circular heel, d = 6.0 mm
radius of the heel, r = 3.0 mm = 0.003 m
Cross-sectional area of the heel is given by;
A = πr²
A = π(0.003)²
A = 2.8278 x 10⁻⁵ m²
The weight of the woman is given by;
W = mg
W = 55 x 9.8
W = 539 N
The pressure exerted by the woman on the floor is given by;
P = F / A
P = W / A
P = 539 / (2.8278 x 10⁻⁵ )
P = 1.9061 x 10⁷ N/m²
Therefore, the pressure exerted by the woman on the floor is 1.9061 x 10⁷ N/m²

A baseball player hits a ball with a bat. At one moment the force exerted by the bat on the ball is 18,000 N. At that same moment, how much force is exerted on the bat by the ball?
a) 18,000 N
b) less than 18,000 N
c) more than 18,000 N
Answer:
Less than 18000N
Explanation:
Given
[tex]Force\ Exerted = 18000N[/tex]
This question will be answered using Newton's third law.
Understanding this law, it implies that reaction force is equal and opposite to the force exerted.
This implies that;
If the force exerted on the ball is 18000N
the force exerted is -18000N
So, the option that answers the question is less than 18000N because -18000N < 18000N

A force of 1.50 N acts on a 0.20 kg trolley so as to accelerate it along an air track.
The track and force are horizontal and in line. How fast is the trolley going after acceleration from rest through 30 cm, if friction is negligible?
Answer: The trolley is moving at 2.12m/s
Explanation:
Given from the question that the track and force are horizontal and inline, we have that
F= ma
where F= force= 1.50 N
m= mass = 0.2kg
therefore Acceleration , a = F/ m= 1.50/0.2 =7.5 m/s^2
To find how fast the trolley is going ie the Velocity, v
Having that
initial velocity at rest , u = 0,
acceleration a = 7.5 and
and distance, s = 30 cm = 30/100 = 0.30 m
we use motion equation that
v² = u² + 2 a s
v² = 0² + 2 x 7.5 x 0.30
v² = 4.5
v = [tex]\sqrt{4.5}[/tex]
v = 2.12 m/s

Two balls collide in a head-on elastic collision and rebound in opposite directions. One ball has velocity 1.2 m/s before the collision, and −2.3 m/s after. The other ball has a mass of 1.1 kg and a velocity of −4.2 m/s before the collision. (a) What is the mass of the first ball? (b) What is the velocity of the second ball after the collision?
Answer:
If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i v 2 f = 2 ⋅ m 1 ( m 2 + m 1 ) v 1 i + ( m 2 − m 1 ) ( m 2 + m 1 ) v 2 i .

D. She could replace the nail in the wire coil with a thick roll of paper.
Correct answer is C!
Answer: i think its c but i am not sure tho but i think its she could replace the 6 v battery with a 12 v battery
Explanation: cause a 12 v is stronger than a 6 v battery
A student made the electromagnet shown and used it to pick up one sewing pin. She then doubled the number of coils around the nail and used it to pick up two sewing pins. She could replace the 6V battery with a 12 V battery.
What is electromagnet?Permanent magnets are not the same as electromagnets. Coils of wire with electricity running through them make up electromagnets. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.
The coils stop functioning as a magnet when the electricity is turned off. A lot of things use electromagnets.
When magnetic forces are only required for brief periods of time, electromagnets are frequently used in electrical equipment.
Therefore, A student made the electromagnet shown and used it to pick up one sewing pin. She then doubled the number of coils around the nail and used it to pick up two sewing pins. She could replace the 6V battery with a 12 V battery.

If you drop a rock off a cliff and it hits the ground 3 seconds later how tall is that cliff
Answer:
Basic kinematics, negating drag and assuming ideal conditions, we use the equation:
d=vi*t+1/2*a*t^2
Since vi is 0 (we know this because you’re dropping it, not throwing it)…
…and the only acceleration acting on it is gravity, a=9.8 m/s^2…
…we get
d=1/2(9.8)(5)^2
Explanation:
Some quick mental math tells us that this is about 125 m.
Plugging it in, we find it to be 122.5 m.

Newton's Third Law predicts that during a collision between two carts, when the sum of the forces acting on the system are zero:
Answer:
The two carts will experience an impulse of the same magnitude, but of opposite directions.
Explanation:
Newton's third law proves that though action and reaction are the same, but they are opposite to each other.
i.e [tex]F_{1}[/tex] = -[tex]F_{2}[/tex]
where: [tex]F_{1}[/tex] and [tex]F_{2}[/tex] have equal value.
Impulse = F x t
where F is the force on the object and t is the time of impact.
In the given question, since the collision takes place in a given time.
Then;
[tex]F_{1}[/tex] x [tex]t_{1}[/tex]= -[tex]F_{2}[/tex] x [tex]t_{2}[/tex]
⇒ [tex]F_{1}[/tex] [tex]t_{1}[/tex]= -[tex]F_{2}[/tex] [tex]t_{2}[/tex]
Thus, since the sum of the forces acting on the system are zero, then the two carts experience an impulse of the same magnitude but opposite in directions.
