You are playing with a bumper car pad. While examining it, you place a 2.0 kg block against a spring, of force constant 1600 N/m, and compress it by 0.22 m, as illustrated. After you release the block, it moves along a horizontal surface for 0.10 m before traveling up a frictionless slope. The coefficient of friction on the horizontal surface is k = 0.50. a) What is the maximum elastic potential energy of the spring (assuming there is no friction under the spring) What is the maximum velocity of the mass?

c) What is the maximum vertical height of the mass up the slope?
