Question

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.)

Answer 1

h(t) = -8(t)2 + 3
h(t) = -16(0.5t)2 + 1.5
h(t) = (-16t2 + 3)/2
h(t) = -16(t/2)2 + 3
