A student is moving to college and packs a box so full that they can’t lift it. The student realizes they can push the box across the slick floor to get it to the door. The student applies a force of 40N to the 20 kg. Assume there is negligible friction between the box and the floor.
Calculate the magnitude of the box’s acceleration.
Your answer should have one significant figure.
According to Newton's laws of motion, the acceleration of the box is
proportional to the applied force.
The magnitude of the box's acceleration is 2 m/s²Reasons:
The given parameters are;
Applied force, F = 40 N
Mass of the box, m = 20 kg
Friction on floor surface = Negligible
Solution;
According to Newton's second law of motion, we have;
Force, F = Mass, m × Acceleration, a
Therefore;
[tex]\displaystyle Acceleration, a = \mathbf{\frac{F}{m}}[/tex]
Assuming the force acts in the direction of motion, we have;
[tex]\displaystyle Acceleration \ of \ the \ box, \ a =\frac{40 \, N}{20 \, kg} = \underline{ 2 \, m/s^2}[/tex]

A 1 kg cart has 5 J of work done on it. If the initial velocity of the cart was 3 m/s, what is the final velocity of the cart?
The final velocity of the cart at the given mass is 4.36 m/s.
The given parameters;
mass of the cart, m = 1 kgwork done on the cart, W = 5 Jinitial velocity of the cart, u = 3 m/sThe distance traveled by the cart is calculated as follows;
Fd = W
mgh = W
[tex]h = \frac{W}{mg} \\\\h = \frac{5}{1 \times 9.8} \\\\h = 0.51 \ m[/tex]
The final velocity of the cart is calculated as follows;
[tex]v^2 = u^2 + 2gh\\\\v^2 = (3)^2 + 2(9.8)(0.51)\\\\v^2 = 18.996\\\\v = \sqrt{18.996} \\\\v = 4.36 \ m/s[/tex]
Thus, the final velocity of the cart at the given mass is 4.36 m/s.

For a wave, the _________ is the distance between two successive crests, while the _________ is the time elapsed between two successive crests passing by the same point.

is the total energy input of a wood fire is equal to the total energy output ?
Answer:
Energy in the campfire originates from the potential chemical energy of the wood, before it is burnt to warm and give light around the campfire.
Explanation:
For a camp fire, the energy input is in the form of the potential chemical energy, stored up in the firewood used to fuel the flame.
The energy output is in the form of heat energy that the campfire radiates all around, light energy given off from the flame, and a little bit of sound energy, heard in the cracking of the firewood as they burn in the flame.
chemical energy ⇒ heat energy + light energy + sound energy
1)Calculate the mass of a girl that has a weight of 113 Newtons.
2)Determine the weight of a boy of mass 13.4 Kg.
could someone help e asap with this
Answer:
Explanation:We should know that weight = mass * gravity.
That is weight equals mass times gravity.
Gravity is a force of attraction between any two bodies in the universe. It is directly proportional to product of their masses and inversely proportional to the square of the distance between them.
Gravity is generally measured in terms of acceleration due to gravity, denoted as g. For Earth it is, 9.8 m/s². And for moon, it is about 1.62 m/s².
On Earth, your weight is 70 kg = W
W = mass x 9.8
70 = mass x 9.8
Your mass is 70/ 9.8
i.e approximately 7.14
Weight at the Moon, W' = 7.14 x 1.62
Hence, your weight on the surface of the moon is just 11.56 kg.
