A wooden block and a gun are firmly fixed to opposite ends ofa long glider mount

Question

A wooden block and a gun are firmly fixed to opposite ends ofa long glider mounted on a frictionless air track (picturebelow). The block and gun are a distance Lapart. The system is initially at rest. The gun isfired and the bullet leaves the gun with a velocityvb and impacts the block, becoming imbedded init. The mass of the bullet is mb and themass of the gun-glider-block-system ismp. (a) What is the velocity of the glider immediately after thebullet leaves the gun? (b) What is the velocity of the glider immediately after thebullet comes to rest in the block? (c) How far does the glider move while the bullet is intransit between te gun and the block?

Explanation / Answer

a) solve the above equation for vp b) vp = 0 since the above equation is stillvalid mb vb - mpvp = o    c) (vb + vb) t = L Use s = vp t to get distance glidertravels b) vp = 0 since the above equation is stillvalid mb vb - mpvp = o    c) (vb + vb) t = L Use s = vp t to get distance glidertravels
