A hollow spherical shell has mass 8.35 kg and radius 0.215 m. It is initially at rest and then rotates about a stationary axis that lies along a diameter with a constant acceleration of 0.910 rad/s2. What is the kinetic energy of the shell after it has turned through 5.25 rev?

f=ma newton

f=100x2.5=250n

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
