A soccer ball accelerates from rest and rolls 6.5 m down a hill in 3.1 s. It then bumps into a tree. What is the speed of the ball just before it hits the tree?

A formula to answer this question would be fine; you don't have to solve the whole thing.

  1. the ball is uniformly accelerated by gravity

    average velocity =
    ... (final vel. + initial vel.) / 2

    6.5 m / 3.1 s = (V fin + 0) / 2
