The height of a baseball (h) in meters (t) seconds after it has been tossed out a window is given by the equation h= -5t^2 + 20t + 15. A boy shoots at the baseball with a trajectory of h= 3t +3. Will the paintball hit the baseball? If so at what height and time?

well, when do you have

-5t^2 + 20t + 15 = 3t + 3?

once you have t, then plut it in to get h.
