As a logging truck rounds a bend in the road, some logs come loose and begin to roll without slipping down the mountainside. The mountain slopes upward at 42.0 degrees above the horizontal, and we can model the logs as solid uniform cylinders of mass 500 kg and diameter 1.20 m.
What is the acceleration (a) of the logs rolling down the hill?
What is the magnitude of the frictional force of the rolling logs?
