Part A) The graph shows the y-component of the velocity (with up chosen as positive) of a ball thrown up with an initial speed of 27.0 m/s from the surface of Mars. What is the magnitude of the acceleration of gravity on the surface of Mars? (NOTE: the y-axis of the graph is labeled "upward speed", but it should say "y-velocity".

Part B) Select ALL correct answers in alphabetical order, i.e., B, AC, BCD...

A) Maximum height is reached at about t=7.3s.

B) The ball's KE increases during the first second.

C) The ball's PE is a constant.

D) v and g are in the same direction after t= 7.3s.

E) The acceleration is 0 near t= 7.3s.

F) The acceleration is constant.

2. Relevant equations

3. The attempt at a solution

I am unsure how to do part A, so if someone could walk me through it that would be great. For part b, I was thinking A was correct, B was correct, D was correct, E was correct. So my answer for part B is ABDE. Does this sound right?
