(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A) The ball's PE is a constant.

B) The velocity vector and the acceleration vector are in the same direction after t= 7.3s.

C) The acceleration is constant.

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

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

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

3. The attempt at a solution

I am pretty sure of the following. Somewhere i am wrong.

A is false

B is true (given once it hits 7.3, gravity is negative(acceleration) and the direction is necative

C is true because accel is gravity and that is always constant.

D is false because if the gravity is constant than it wouldnt be zero

E is true because it starts coming down after 7.3 s

F is true because KE is zero when the ball is in hand but when he releases it, it gains
