Assume that, for safety, the car is launched with an initial velocity that is 10% greater than the minimum launch speed, and maintains this velocity throughout its motion What will be the magnitude of the force of the track on the car when the car is at the top of the loop?

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
