Question

Show that j=m∆v.J is the impulse acting on a body of mass m and ∆v is change in velocity

Answer 1

Impulse is defined as the rate of change of momentum

velocity=v

mass=m

We know that momentum p=m×v

Impulse is rate of change of momentum and it is given that mass is constant , therefore impulse will be equal to change in velocity

impulse j= m×change in velocity
