What is the speed of the block just as it touches the spring

Reference no: EM13533867

A spring can be compressed 2.0 cm by a force of 329 N. A block with a mass of 9.0 kg is released from rest at the top of a frictionless incline as shown. The angle of the incline is 30.0°. The block comes to rest momentarily after it has compressed the spring by a distance d=5.5 cm.

a) What is the distance L which the block has moved down the incline at this moment?

b) What is the speed of the block just as it touches the spring?
