Pulling a block up a ramp

Motion on an incline plane

Explanation:

A number of forces are acting on the box, including both gravity and friction, and you need to take both into account. There’s also the force exerted upon the box as you push it up the ramp.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
