5) BB-8 is an intergalactic robot that is trying out for a new role in the rebellion. The main portion of his body is a sphere of radius half a meter. One competition tests how quickly entrants can travel 250 m. They must start from rest and end at rest. BB-8 has a maximum angular acceleration rate of 1.9 rad/s2 , both when speeding up and slowing down. (a) What is the corresponding torque on BB-8’s solid spherical body, assuming it has a mass of 4.6 kg? (b) What is the minimum time in which BB-8 can run the trial? (c) What is the maximum number of revolutions per minute BB-8 obtains in this competition?
