Bill throws a 10.0-g ball straight down from a height of 2.0m. The ball strikes the floor at a speed of 7.5m/s. What was the initial speed of the ball.

2. Relevant equations

Can you provide the proper formula and solution to solve this problem?

3. The attempt at a solution

I tried using the following formula, but realized it was probably wrong.

vf2= vi2 +2gd

Vf and vi are to the second power

g= gravity acceleration 9.8

d- displacement
