The ball has a mass of 30 kg and a speed v = 4 m>s at the instant it is at its lowest
Chapter 13, Problem R13-5(choose chapter or problem)
The ball has a mass of 30 kg and a speed v = 4 m/s at the instant it is at its lowest point, \(\theta = 0^{\circ}\). Determine the tension in the cord and the rate at which the ball’s speed is decreasing at the instant \(\theta = 20^{\circ}\). Neglect the size of the ball.
