A bullet of mass m= 0.0230 kg is fired along an incline and imbeds itself quickly into a block of wood of mass M= 1.30 kg. The block and bullet then slide up the incline, assumed frictionless, and rise a height H= 1.20 m before stopping. Calculate the speed of the bullet just before it hits the wood. Note. The block is kept from sliding down the incline initially by as small peg.
