Question

A wooden block with mass 1.85 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 7.55 m up the incline from A, the block is moving up the incline at a speed of 6.55 m/s and is no
longer in contact with the spring. The coefficient of kinetic friction between the block and incline is u4 = 0.40.
Part A
The mass of the spring is negligible.
Calculate the amount of potential energy that was initially stored in the spring.
