Question

can someone help me this problem so that i can understand fully well. thank you
subject:dynamics of rigid bodies

The ball has a mass of 30 kg and a speed v = 4 m/s at the instant it is at its lowest point, 0 = 0°. Determine the tension in the cord and the rate at which the ball's speed is decreasing at the instant 0 = 20°. Neglect the size of the ball. 4 m
