Dimitri has the ball on the ground 27.5 meters away from
Oliver. Dimitri kicks the ball toward Oliver with an initial
upward velocity of 12.25 meters per second and Oliver heads
it into the net on its way back down at a height of 2.64
meters. Ignoring wind resistance, use the formula
h(t) = -4.9t2 + v0t + h0 where h(t) is the height of the ball, v0 is
the initial upward velocity, and h0 is the initial height of the
ball, to determine how long it took the ball to reach Oliver.
