A pulley of diameter 49.0 in revolves at 1860 rpm. What is the diameter of a second pulley, in inches, if it rotates at 620 rpm?

If this speed is based on what would be safe in wet weather, estimate the radius of curvature for a curve marked 50 km/h. The coefficient of static friction of rubber on wet concrete is μs=0.

A 40 N crate rests on a rough horizontal floor. A 12 N horizontal force is then applied to it. If the coecients of friction are μs=0.5 and μk=0.4, the magnitude of the frictional force on the crate is:
