Physics

A bullet of mass m=20 gr is fired into a block of mass M=5 kginitially at rest at the edge of a frictionless table of heighth=0.90 m. The bullet remains in the block and the block lands adistance d=0.68 m from the bottom of the table. Picture1a)Determine the initial velocity of the bullet. vi= m/s b)Determine the loss of kinetic Energy during the collision. ΔK =J.
