Step 1
The ball starts on the floor (height = 0 m). Hanging from a 1.0 m string from a ceiling 5.0 m above the floor, the ball's final height = 5.0 m - 1.0 m = 4.0 m. Show more…

A bowling ball of mass m is attached to the ceiling by a rope of length L. The ball is pulled to the side and released, swinging to and fro. At the bottom of the swing, the ball has speed v. (a) Write an equation for the tension in the rope at the bottom of its swing. (b) Calculate the rope tension at the bottom of the swing for a 7.3 kg ball moving at 4.3 m/s at the end of a 2.0 m long rope.
