Explanation:
to find the theoretical velocity Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds ,
Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .(s=d/t) and to find the actual velocity use this formulae
h=v0*t+ 1/2 at^2
