## Homework Statement

You toss a ball up in the air with an initial velocity of 6 m/s (immediately after leaving your hand). Use gravity = -9.8 m/s2.

What is its acceleration immediately after releasing the ball?

What is its velocity at its peak height?

What is its acceleration at its peak height?

What is the ball's velocity when it falls past the point at which you released it?

## Homework Equations

d=v0t+1/2gt^2

v=v0+at

v^2-v0^2=2gd

## The Attempt at a Solution

I got the first three answers (-9.8, 0, -9.8, respectively), but I'm confused about the last question. I tried solving for distance of the ball going up to the top and tried to use that....I also tried plugging in the numbers for the equations with v0=0m/s b/c that was the velocity at the top of the arc...I'm not sure if I'm even on the right track at this point...
