Question

A bullet of mass o.2kg is
moving with a speed of 200 metre per second and then get inserted into a block of 5 kg and block started moving with 50 metre per second. find change in momentum ?
​

Answer 1

Answer:

150m/s-1

Explanation:

here, m1=0.2kg,v1=200m/s-1,m2=5kg,v2=50m/s-1

m1v1-m2v2=change in momentum

=0.2*200-5*50

=400-250

=150m/s-1
