Question

A can of juice rolls down a ramp with angle 80 degrees. If the slope were frictionless the can would slide down the incline without rolling. Calculate the minimum coefficient of static friction needed for the can to roll down the incline. Model the can as a cylinder of mass 500 g, radius 10 cm and length 32 cm. Hint: Use Newton's Second Law
