1. Draw a diagram showing the forces acting on the ball at the instant when it is released from a height h = 10 cm.
If the length of the string is 1 m, calculate the angle made by the string with the vertical when h = 10 cm
If the mass of the ball is 60 g, what is the tension on the string when h = 10 cm?
What is the tension on the string when the ball fall back to its original position from a height h = 10 cm
2. What will be the value of h when the string makes an angle of 90o with the vertical?
What will be the tension on the string when the mass is at this height?
If the mass is now allowed to fall from this height, what will be its velocity when it returns to its initial position?
What is the work done by gravity on the ball when it is released from this height?

1. (20 points) A pendulum consists of a small ball of mass m=2.00 kg that is suspended from a fixed point by a light string of length L=0.850 m (like the demonstration video.) The pendulum is released from rest when it is in its initial position with 0 =65.0°. Air resistance is negligible. a) Calculate the work done by gravity as the ball moves from the highest point of its semicircular path to the lowest point of its path. b)...
