A 25 g bullet is fired from a gun into a 1.35 kg block of wood initially at rest. (The bullet sticks in the wood). The wood is driven 9.5 m across a horizontal surface with coefficient of friciton 0.25. Find the speed of the bullet just before impact.

A bullet of mass 5 g with velocity 1000m/s hits a wooden block of 1.5kg at rest. If the bullet penetrates through the block with a velocity of 400m/s, calculate the maximum height in which the block is lifted from its initial position.
