Use the function h = -16T2 + vT + s for all problems in feet. Use the
function h = -4.9T2 + vT + s when given in meters.
1) A football is kicked straight up from a height of 4 feet with an initial speed of
60 feet per second. The function f(t) = -16t2 + 60t + 4 models the ball’s height
above the ground, f(t), in feet, t seconds after it was kicked.
A) How long will it take for the football to hit the ground?
B) How high did the ball travel?
C) What time did it get to its highest height?
D) What height was the ball kicked from?
