1. The problem statement, all variables and given/known data
A tennis player tosses a tennis ball straight up and then catches it after 2.00 s at the same height as the point of release. (a) what is the acceleration of the ball while it is in flight? (b) what is the velocity of the ball when it reaches its maximum height? Find (c) the initial velocity of the ball and (d) the maximum height it reaches.


2. Relevant equations



3. The attempt at a solution

Have you tried anything thus far? What equations do you know that relate your unknown variables?

I honestly do not know where to start... I'm so lost in physics right now.

I would assume you are to neglect air resistance so a good place to start would be constant acceleration formulas.

a= v-v0/t ?.

that sounds good... you know your v after t=2...

I don't know my velocity though

what is your v at t=2?

Zero? Right because the ball is caught after 2 seconds in the same position it was thrown...

Spot on! now you have only v0 and a to find, there might be some other formulas that you can compare to this one. Keep going and you'll figure it out.
