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

A baseball, thrown from shortstop position to first base travels 32m horizontally, rises 3mm and falls 3m. Find the velocity of the ball.

2. Relevant equations

d=v(t)+0.5(a)(t)^2

3. The attempt at a solution

So i know horizontal motion will be a constant velocity and vertical will have acceleration

(-9.8m/s/s)

For the equation i know d=2.997m, a=-9.8m/s/s but there are still two unknowns. I was thinking of substitution or elimination to get rid of a variable, with anything i sub in has a variable so it gets no where.

If there was one more given it would be easy, but i cant get anywhere with just displacement other then the time it takes just to drop it (which should be the time when its dropped 3mm to the ground but i dont know that smaller distance.

Gan somebody help me with what my next step should be?
