5. On the planet of Vormir, the acceleration of gravity is negative 4 meters per second per second. You drop a stone off the top of a 50 meter cliff. Initially the stone has a velocity of 0 meters per second, but it is accelerating downwards due to gravity.

(d) What is the velocity of the stone when it hits the ground? (e) Find the velocity and position equations if instead of dropping the stone, I threw it upwards with an initial velocity of 10 meters per second.
