A wooden block with mass 1.50 kg is placed against a compressedspring at the bottom of an incline of slope 30.0° (point A). Whenthe spring is released, it projects the block up the incline. At point B, adistance of 6.00 m up the incline from A, the block is moving up the inclineat 7.00 m/s and is no longer in contact with the spring. The coefficientof kinetic friction between the block and the incline is mk = 0.50.The mass of the spring is negligible. Calculate the amount of potentialenergy that was initially stored in the spring.

Question
A wooden block with mass 1.50 kg is placed against a compressed
spring at the bottom of an incline of slope 30.0° (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 7.00 m/s and is no longer in contact with the spring. The coefficient
of kinetic friction between the block and the incline is mk = 0.50.
The mass of the spring is negligible. Calculate the amount of potential
energy that was initially stored in the spring.
