A ball is thrown up at 13.0 m/s near the edge of a 30.0-meter high cliff. The ball lands at the bottom of the cliff.
a) What is the acceleration of the ball just after it is thrown (magnitude and direction)?
b) What is the acceleration of the ball at the peak of its trajectory (magnitude and direction)?
c) What is the velocity of the ball just before impact at the bottom of the cliff?
d) How much time after being thrown does the ball take to land?
