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

A rock thrown straight up climbs for 2.50 s, then falls to the ground. Neglecting air resistance, with what velocity did the rock strike the ground?

2. Relevant equations

well we are looking for v=?

we have:

t=2.50 s

and g=9.8

^do we need gravity? yes, right? =S

3. The attempt at a solution

v= d/t

well we only have the time.

so we have to look for the distance... but the distance is ?

do we have to calculate another equation.

ahh please guide me to my answer. :S

thanks.
