When a force of 4 N acts on a mass of 2 kg for a time of 2 sec, what is the rate of change of momentum?
Correct answer: C. 4 kg·m/s2
- A. 2 kg·m/s2
- B. 8 kg·m/s2
- C. 4 kg·m/s2
- D. 16 kg·m/s2
Explanation
The rate of change of momentum (also known as force) can be calculated using the formula: F = Δp/t, where Δp is the change in momentum. In this problem, since force is already given as 4 N, and the rate of change of momentum is equivalent to the applied force, the correct answer is 4 kg·m/s2. Options A, B, and D are incorrect because they misinterpret the relationship between force, time, and momentum.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
