Problem 1: A 2.0 kg block slides down a plane that is incline at an angle of 30 degrees with respect to the horizontal. When the block is at a height h= 5.0 meters, it has an unknown speed V. At the bottom of the incline the block hits a relax spring that has a force constant k = 1000 N/m and compresses the spring a maximum distant x = 0.50 meters. If the coefficient of kinetic friction between the block and the incline is 0.25, what was the speed (V) of the block at the 5.0 m height. Use conservation of mechanical energy to solve this problem.
