Question

A body of mass 50 kg moves with an acceleration of 4 m/s². The rate of change of momentum in Sl unit is​

Answer 1

Answer:

Mass of the body, m = 20 kg

Acceleration, a = 2

m/s^2

Using Newton's second law of motion, force equals rate of change of momentum.

ans=40 N

Answer 2

Rate of change of momentum is 200 N

Given - Mass and acceleration

Find - Rate of change of momentum

Solution - As per the Newton's second law of motion, the rate of change of momentum is equal to the impulse or force applied. Representing this in equation form -

Rate of change of momentum = Force applied

Force applied = mass × acceleration due to gravity

Keep the values in formula to find the rate of change of momentum

Rate of change of momentum = 50 × 4

Performing multiplication

Rate of change of momentum = 200 N

Hence, the rate of change of momentum is 200 N.
