### A wooden block with mass 1.50 kg is placed against a compressed spring at the bottom of an incline of slope 30.0 degrees. When the spring is released, it projects the blockup the incline. At point B, a distance of 6.00 m up the incline from A, the block is moving up te incline at 7.00 m/s andit is no longer in contact with the spring. The coeffiicient of kinetic friction between the block and incline is k =0.50. The mass of the spring is negligible. Calculate the amount of potential energy that wasinitially stored in the spring.
