A) how large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius 125m at a speed of 95km/ h? B) a 15.0 kg child is riding a playground merry go round that is rotating at 45 rpm. What centripetal force must she exert to stay on if she is 1.00 m from its center? C)what centripetal force does she need to stay on an amusement park merry go round that rotates at 3.00 rpm if she is 8.50m from its center?
