Question

A bullet of mass 7 g is fired into a block weighing 7 kg, which is free to move. Calculate initial velocity of bullet if the velocity of the block with the bullet inside is 0.7 m/s.​

Answer 1

Answer:

By considering the conservation of momentum

m1*V1 = (m1+m2)*v

finding V1,after substuting the values

m1= 7g

m2=7000g

v=0.7 m/s

we get V1=700.7 m/s
