Question

Q) A force of 100  Newton acts on two objects of masses 5 kg and 10 kg moving with initial velocities  of 2 metre per second and 10 metre per second respectively. If the force acted on both bodies for 10 second. Calculate the change in momentum of 5 kg object. ​

Answer 1

Answer:

Correct option is

500 m s

−1

Given : F=100 N m=2 kg t=10 s

Change in momentum of the body m(Δv)=F.t

where Δv is the change in velocity.

⟹ 2×Δv=100×10

⟹ Δv=500 m/s
