Question

A 5 kg object has a net force of 10 N acting on it. What is the rate at which the object's momentum increases?

Answer 1

Given data:

* The mass of the object is 5 kg.

* The net force acting on the object is 10 N.

Solution:

By the Newton's second law, the force acting on the object in the terms of rate of change of momentum is,

`F=(dp)/(dt)`

dp is the change in momentum, and dt is the small interval of time.

The rate of change of momentum is equal to the force applied.

Thus, the rate at which the momentum increases is 10 N.
