A spring of spring constant 11,000N/M is compressed by a block of mass 3kg is released from rest at the top of the incline plane. the friction coefficient between the block and the surface of the incline is 0.2. the block comes to rest momentarily after it has compressed the spring by 5 cm

a) how far has the block moved down the incline?

b) what is the speed of the block jsut as it touches the spring?
