As part of a child's game, a girl swings a ball on the end of a string in a horizontal circle with constant speed, as shown in (Figure 1). The string is 0.3m long and makes an angle of 35∘ with the vertical during the game, and the mass of the ball is 100g. What is the speed of the ball? During half a revolution, what is the work done by gravity and tension on the ball?
