1. The problem statement, all variables and given/known data A 2.9 kg block is released from rest and allowed to slide down a frictionless surface and into a spring. The far end of the spring is attached to a wall, as shown. The initial height of the block is 0.32 m above the lowest part of the slide and the spring constant is 442 N/m. (a) What is the block's speed when it is at a height of 0.25 m above the base of the slide? ________ m/s (b) How far is the spring compressed? _______ m (c) The spring sends the block back to the left. How high does the block rise? _________ m 2. Relevant equations PEi+KEi=PEf+KEf and PEi+KEi+1/2Kxi^2=PEf+KEf+1/2Kxf^2 3. The attempt at a solution For A, How do you set up the equations so you find the final velocity at that point?
