Question

A bag of sand of mass m suspended by a rope a bullet of mass m/40 is fired at with in a speed of v and gets emailed into it then find velocity of the bad

Answer 1

there is not any information provided about the bad in the question

please correct ur question....

Answer 2

Answer:

Explanation:

Given that

Mass of sand bag = M

Mass of bullet = m

Initial velocity of bullet before striking the bag = v

Lets the final velocity of bullet and bag is u because they will move together.

We know that there is not any external force so the linear momentum will be conserve.

m v =(M+m)u

So  u=m v/(m+M)

Initial kinetic energy  of system

Final kinetic energy  of system

So the loss in kinetic energy
