Q13. As shown in the image below, the 54 kg-crate is initially at rest, and at a distance d= 6.0 m from the top of the spring. Then it slides down the inclined plane. If the coefficient of kinetic friction between the crate and the inclined plane is uk = 0.22, determine the compression of the spring, x, when the crate momentarily stops (as the spring reaches maximum compression). The spring has spring constant k = 1.3 kN/m and initially the spring is unstretched. Please pay attention: the numbers may change since they are randomized.
