Question

A body of mass m is moving with a velocity when a force is applied on it for time t, then its velocity increases to v,
Write expression for:
i) Initial and final momentum
ii) Change in momentum
iii) Rate of change of momentum​

Answer 1

Explanation:

As we know that momentum (p) =MAASS×VELOCITY(vector quantity)

hence chance in momentum(Δp)=m

=Δ(mv)

where m

=m

Δv=v
