Homework Statement
A 15g bullet is fired from a gun, leaving the gun with a muzzle velocity of 750m/s. It hits and sticks in a 1250g wooden block. The block is on a table 5.0m away from edge. The table is 1.1m above the floor and between the block and the table surface constant of kinetic friction is 0.50. Will the block slide off the table and if so what will be the horizontal distance from the block to the table base when the block hits the floor?
Homework Equations
Momentum equation , dynamics, friction and Fg
The Attempt at a Solution
so basically we find the intial velocity of wooden block with the help of given data of bullet b/c momentum has been conserved. so block is moving. or maybe m wrong. this question has confused me. suppose the block is moving then how do we know how far it will go. I have some idea but how do i derive equations and find the answer,
Plzz help. Its very important.
