An amusement ride consists of a car moving in a vertical circle on the end of a rigid boom. The radius of the circle is 32 meters. The combined weight of the car and riders is 6.2 kNewton. At the top of the circle the car has a speed of 3.8 m/s. which is not changing at that instant. What is the force of the boom on the car at the top of the circle?
