5. Suppose Mr. Lanier puts a 0.60-kg rock into a sling of length 1.5 m and begins whirling the rock in a nearly horizontal circle, accelerating it from rest to a rate of 75 rpm after 5.0 s. What is the torque required to achieve this feat? (Treat the rock as a particle.) Also, tell me why you think Mr. Lanier is whirling a rock around in the air.
