Part A A wooden block with mass 1.65 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 29.0 (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 5.70 Calculate the amount of potential energy that was initially stored in the spring. m up the incline from A, the block is moving up the incline at a Express your answer in joules. speed of 6.10 m/s and is no longer in contact with the spring. The coefficient of kinetic friction between the block and incline is uk = 0.45. The mass of the spring is negligible. VO AEQ ?
