    Here's the question:

    A 2.0 kg ball swings in a vertical circle on the end of an 80-cm-long string. The tension in the string is 20 N when its angle from the highest point on the circle is theta = 30 degrees.

    (a) What is the ball's speed when theta equals 30 degrees? (in m/s)

    (b) What is the magnitude of the ball's acceleration when theta equals 30 degrees? (in m/s^2)
