The rope connected to it passes through a hole in the table at the center of the circle and is connected to another mass M' below the table. Determine M. 7: A 2 kg ball connected to a string moves in a vertical circle of radius 0.75 m (above right). At the bottom of the circle the ball has a speed of 7 m/s. Determine the magnitude of the tension in the string at points A, B, C and D. 8a: A car is moving in a circular path of radius r. Determine the maximum speed the car can have and still stay on the road if friction between the car and the road is described by [[13, b: Evaluate your answer to a if [1.5 : 1.5 (good tires on a dry road) and if {is : 0.1 (icy conditions). Assume that r : 50 m. c: Some bends on mountain roads and some bends in races like the Daytona 500 are banked. \\Nhat forces help keep the car moving in a circle? Explain
