On a planet that has no atmosphere a rocket 15.4 meter tall is resting on its launch pad. The acceleration due to gravity on this planet is 5.45 m/s^2. A ball is dropped from the top of the rocket with zero initial velocity.

a) Find how long does it take the ball to reach the launch pad?

b) Find what is speed of the ball just before it reaches the ground?
