Simple theoretical Mechanical Energy question

What is the answer to only the letter e in the following?:

"A 0.5kg rubber ball is thrown into the air. At a height of 20m above the ground, it is trabelling at 15m/s.

(a) What is the ball's kinetic energy?
(b) What is its gravitational potential energy relative to the ground?
(c) How much work was done by someone at ground level throwing the ball up into the air?
(d) What was the speed of the ball when it left the ground?
(e) Do your answers depend on the ball's direction?"

Any help would be greatly appreciated!
Thanks in advance!

energy has no direction and it does not depend on direction

this is one of the huge advantages to using energy to calculate rather than using velocity formulas where you would have to pay attention to the direction(sign) on your numbers
