Transcribed Image Text:

A wooden block with mass 1.75 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 28.0° (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 7.90 m along the incline from A, the block is moving up the incline at a 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 = 0.450. If the spring constant of the spring used is 40 000 N/m, what was the compression of the spring at the bottom of the incline, in meters? Use energy methods to solve this problem.
