Question

an object of mass 2kg is moving with velocity of 80m/sec stops after 10sec. calculate it's initial and final momentum​

Answer 1

solution:

given m=2kg initial velocity (u) =80m/s

initial momentum= P1=mu

putting the values,we get

P1=2×80=160kg m/s

after 10 sec it stops means final velocity is 0

according to formula P=mv momentum also will be 0
