Solve the problem.
A ball is kicked upward with an initial velocity of 68 feet per second. The ball's height, h (in feet), from the ground is
modeled by h= -16^2+68t, where t is measured in seconds. How much time does the ball take to reach its highest
point? What is its height at this point?
a. 4.25 sec; 72.25 ft
b. 4.25 sec; 216.75 ft
c.
d.
2.125 sec; 144.5 ft
2.125 sec; 72.25 ft
