Question

Review question:

A 48g bullet is fired with a speed of 500 m/s into a 3.6 kg sandbag pendulum that is free to swing. To what maximum vertical height will the endulum rise? Assume the bullet remains mbedded in the sandbag and that the rope is long.

Answer 1

kinetic energy of billet is
(1/2)mv^2=0.5*48*10^-3*500^2

Answer 2

this kinetic energy of a bullete will b equal to the potentisl energy of sandbag

Answer 3

yeah i did that, but i did not get the right answer.
the answer is 2.2 m

Answer 4

ok

Answer 5

so how to get the right answeR?

Answer 6

i m trying

Answer 7

now potential energy of sandbag with bullete is

Answer 8

mgh=(3.6+48*10^-3)*9.8*h

Answer 9

did u c the value of m
