Homework Statement
A 2.25g bullet embeds itsself in a 1.50kg block, which is attached to a spring of force constant 785N/m. If the max compression of the spring is 5.88cm, find the initial speed of the bullet and the time for the bullet block system to come to rest.
The speed comes out to be 897.43m/s
Homework Equations
mvi=mvf
1/2mv^2=1/2kx^2
T=2∏√m/k
The Attempt at a Solution
I was able to find the initial speed of the bullet and only got stuck on the second part. I thought that since I'm given the distance and I found the speed of the bullet and block system, I could divide them to get the time.
The other time equation did not work either. Please help!
