Question

Initial momentum of a particle is found to be 20 Ns. After 5 seconds, momentum was found to be 55 Ns.
Find average force acting on the particle.​

Answer 1

Answer:

7N

Explanation:

Newtons second law of motion states that;

the net external force acting on an object is equal to the time rate of change of objects momentum.

i.e F net = ∆P/ ∆T

∆P= 55-20= 35

∆T = 5 sec
