A short stop makes an error by dropping the ball. As the ball drops, its height h in feet as a function of time, t, is modeled by h(t) = -16t2 + 3. A slow motion replay of the error shows the play at half speed. What function describes the height of the ball in the replay? (Hint: The function squares the time, so half the time is also squared in the new function.) Please help, I've tried everything, but the answers are all wrong! D:

Question

anonymous · Answer

h(t) = -16(1/2*t)^2 + 3
simplify
h(t) = -16*1/4*t^2 + 3
h(t) = -4t^2 + 3
