ANSWER: 17 m
5.) The graph of an object's position over time is a horizontal line and y is not equal to 0. What must be true about the object's motion?
ANSWER: The velocity is zero.
hope this helps <3
As the graph shows, position over time is a horizontal line and y is not equal to 0 then the velocity is zero. Hence, option A is correct.
What is Acceleration?Acceleration is the rate at which the speed and orientation of a moving object change over time. When a spot or object moves faster or slower along a straight line, it is said to be accelerated. Even though the speed is constant, motion on a circle accelerates so because the direction is always shifting. Both by and to acceleration for all other types of motion.
It is a vector quantity because it has both magnitude and direction.
If the graph of an object's position over time is a horizontal line also y is not equal to 0 then it means that the velocity is zero, it cannot be constant or non-zero.
Therefore, it concludes that the velocity is zero and option A is correct.

g A small ball is tied to one end of a light 2.5-m wire, and the other end of the wire is hooked to the ceiling. A person pulls the ball to the side until the wire makes an angle of 35° with the plane of the ceiling and then gently releases it. What is the angular speed of the ball, in rad/s, as it swings through its lowest point?
The angular speed of the ball as it swings through its lowest point is 1.8 rad/s.
The given parameters;
radius of the circular path, r = 2.5 m
angle with the vertical, θ = 35⁰
The angular speed of the ball, as it swings through its lowest point is calculated as follows;
[tex]Tcos \theta = m\omega ^2 r\\\\mgcos \theta = m \omega ^2 r\\\\gcos \theta = \omega ^2 r\\\\\omega ^2 = \frac{gcos \theta }{r} \\\\\omega = \sqrt{\frac{gcos \theta }{r} } \\\\\omega = \sqrt{\frac{9.8 \times cos (35) }{2.5} } \\\\\omega = 1.8 \ rad/s[/tex]
Thus, the angular speed of the ball as it swings through its lowest point is 1.8 rad/s.

Imaging playing a game of baseball on the moon, which has less gravity than Earth and no atmosphere. How would you want to change the game to make it play fairly and fun?
Answer:
In order to reduce the mass of the bat and raise the mass of the ball, the transfer of momentum could only be extended to a distance equal to the size of a baseball stadium. Although the ball's acceleration stays constant regardless of its mass (provided that the mass is less than the mass of the moon), your running time around the bases will be reduced as a result of the increased mass of the ball.

A spring of spring constant k=500 N/m is elongated from its initial length by a distance x=2 cm, then the force applied by the spring is:
A. F= 3N.
B. F= 10 N.
C. F=500 N.
D. F= 0N.
Answer:
1.96 kg * m2/s2
Explanation:
I'm assuming that you are asking what is the elastic potential energy stored in the spring at the position stretched by 16.5 cm...
Since you know the spring constant k, 144 N/m and the spring stretch from the equilibrium position x, is 16.5 cm, or 0.165, you find the spring's potential energy from the equation PE = 12kx2, which equals 1.96 Joules, or kg * m2/s2 if you want SI units.

Obtain Center of Mass:
Obtain the center of mass of an axis of a thin wire with a curve defined by [tex]y=f(x)=x^{3/2}[/tex] from x=0 to x=1 and a lineal density of mass of [tex]p(x)=x^{2}[/tex]
Hi there!
To find the center of mass:
[tex]com = \frac{1}{m}\int\ {rdm}[/tex]
We can begin by changing "dm" into an available quantity by expressing the lineal density as a function:
[tex]\lambda = x^2 = \frac{m}{x}\\\\x^2 = \frac{m}{x}\\\\x^3 = m \\\\[/tex]
Differentiate both sides:
[tex]3x^2dx = dm[/tex]
Let:
[tex]r = f(x) = x^{3/2}[/tex]
Thus:
[tex]com = \frac{1}{m} \int x^{3/2}3x^2dx\\\\com = \frac{1}{m} \int }3x^{7/2}dx\\[/tex]
Evaluate:
[tex]com = \frac{1}{m} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right.[/tex]
We found 'm' above, so plug the expression in:
[tex]com = \frac{1}{x^3} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right. \\\\com = \frac{1}{x^3} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right. \\\\com = \frac{2}{3}x^{3/2}\left \| {{1 \atop {0}} \right. = \boxed{\frac{2}{3}}[/tex]

a car has a displacement of 480 kilometers to the east in 8 hours . What it’s the velocity per hour?
Answer:
The velocity is 60 km/hr.
Explanation:
Given:Displacement (d) = 480 km = 48000 m
Time (t) = 8 Hours = 480 minute
Velocity (v) = ?
Now,
Velocity = Displacement ÷ Time
v = d/t
v = 480/8
v = 60 km/hr
Thus, The velocity is 60 km/hr.

Si la masa es 15.0 kg y la aceleración es 3.0 m/s^2, halla la fuerza en Newton.
By applying Newton's Second Law of Motion, the force acting on the mass is 45.0 Newton.
Given the following data:
Mass = 15.0 kilogramsAcceleration = 3.0 [tex]m/s^2[/tex]To determine the force acting on the mass in Newton, we would apply Newton's Second Law of Motion:
Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the physical object or body, and inversely proportional to its mass.
Mathematically, Newton's Second Law of Motion is given by this formula;
[tex]Force = mass \times acceleration[/tex]
Substituting the given parameters into the formula, we have;
[tex]Force = 15.0 \times 3.0[/tex]
