a baseball hit into the air, and its height s in feet after t seconds is given by s(t)=-16t^2+112t+2

Question

What is the height of the baseball when it is hit. Please break it down for me so I can better understand it.

Answer 1

When the ball is hit, t=0. The answer will be found by substituting 0 for t in the equation of motion, i.e. find s(0).
