You compress a spring with k = 3000 N/m a distance of 0.2 m with a block of mass 4 kg. You then release the block. It slides along a frictionless surface and then goes up an incline of 35 degrees.
a. What is the velocity of the block after it leaves the spring but before it gets to the incline?
b. How far up the incline (along the hypotenuse of the triangle) does the block travel?
