Question

The figure below shows a ball of mass m=1.9 kg which is connected to a string of length L=1.5 m and moves in a vertical circle. Only gravity and the tension in the string act on the ball. If the velocity of the ball at point A is v0=10.4 m/s, what is the tension T in the string when the ball reaches the point D?
