Question

A baseball is thrown upward at an initial speed of 7.0 m/s. The approximate height of the baseball, h metres, after t seconds is given by the equation h = -4.9t² + 7.0t +1. At the same time, a golf ball is hit upward at an initial speed of 13.8 m/s. The approximate height of the golf ball, h metres, after t seconds is given by the equation h = -4.9t² + 13.8t.
After a short time, both balls are at the same height. To the nearest tenth of a metre, what is this height?
