A tennis ball on Mars, where theacceleration due to gravity is 0.379 of a and air resistance isnegligible, is hit directly upward and returns to the same level7.30 later.

how high above its original point did the ball go? how fast was it moving after it was hit? *i am really struggling with this problem. i tried it bydividing the time by 2 and finding where the final velocity wasequal to 0 and i kept getting 2.52 for an answer.... the websitesays im wrong. what did i do wrong?
