A ball on a string is being whirled around overhead when the string breaks.  The ball will move in the direction of the centripetal force the moment the string breaks. T/F?

2. It takes a 615 kg car 14.3 s to travel at a uniform speed around a level circular path of 50.0 m radius. (a) What is the speed of the car? (b) What is the acceleration of the car? (c) What amount of centripetal force must the track exert on the tires as it moves in the circle?

3. A ball is swung in a vertical circle such that at one point along its circular path the forces exerted on the ball can be represented by the free body diagram. The magnitude of the tension force exerted on the ball, T, is twice that of the force due to gravity exerted on the ball from Earth, F. What is the For T location of the ball, and what is the magnitude of the centripetal acceleration of the ball in terms of g? Location Acceleration A. Bottom of the circle g B. Bottom of the circle 3g C. Top of the circle D. Top of the circle 3g

Question 1: #24   The passengers in a roller coaster car feel 50% heavier than their true weight as the car goes through a dip with a 30 m radius of curvature. What is the car's speed at the bottom of the dip?
