On earth's surface, an object weighing 49 N moves in a circular path of radius 0.50 meters. It takes 0.314 seconds to complete one revolution. (Note: A revolution is the time to travel one entire path around the circumference.) Calculate each of the following quantities. Show equation, substitution with units, and answer with units for each: a) mass b) tangential velocity c) centripetal acceleration d) centripetal force e) Draw the vectors for v, ac, Fc onto a diagram (circle)
