Solved: A wooden block with mass 1.50 kg is placed against
Chapter 7, Problem 7.81(choose chapter or problem)
A wooden block with mass 1.50 kg is placed against a compressed spring at the bottom of an incline of slope (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 6.00 m up the incline from A, the block is moving up the incline at and is no longer in contact with the spring. The coefficient of kinetic friction between the block and the incline is The mass of the spring is negligible. Calculate the amount of potential energy that was initially stored in the spring.
