A force of 10 N acts on a body of mass 5 kg for one second, then its time rate of change of momentum will be:
Correct answer: A. 10 kgms-2
- A. 10 kgms-2
- B. 5 kgms-2
- C. 50 kgms-2
- D. 2 kgms-2
Explanation
According to Newton's Second Law of Motion, the time rate of change of momentum of a body is equal to the net force acting on it. Here, the force applied is 10 N, which means the rate of change of momentum is 10 kgms-2. The other options either incorrectly calculate or misinterpret the relationship between force and momentum change. Option B assumes a smaller force, Option C incorrectly suggests a multiplication of values, and Option D assumes a much smaller force than given.

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.
