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 35.0 ° (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.45 m up the incline from A, the block is moving up the incline at a speed of 6.05 m/s and is no longer in contact with the spring. Part A Calculate the amount of potential energy that was initially stored in the spring. The coefficient of kinetic friction between the block Express your answer in joules. and incline is lk = 0.50.
