A group of kids come across a covered bridge that is a great spot for jumping off,
but they want to make sure they stay safe so they want to check how high the
bridge is before anyone jumps off. They find a 5kg rock and guess that it will
experience a coefficient of friction of 0.21 as it falls. Once the rock is thrown over
the edge of the bridge, it takes 1.6s to reach the water.
How tall is the bridge?
