1. A bowling ball rolls without slipping up a ramp that slopes upward at an angle beta to the horizontal. Treat the ball as a uniform, solid sphere, ignoring the finger holes.

What is the acceleration of the center of mass of the ball?

What minimum coefficient of static friction is needed to prevent slipping?

2. An electric motor consumes 11.2 kJ of electrical energy in 1.00 min.

If one-third of this energy goes into heat and other forms of internal energy of the motor, with the rest going to the motor output, how much torque will this engine develop if you run it at 3000 rpm?
