Solve the problem. A ball is kicked upward with an initial velocity of 32 feet per second. The ball's height, h (in feet), from the ground is
modeled by h =-161+ 326. 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. 2 sec; 16 ft
c. 1 sec; 32 ft
b. 1 sec; 16 ft
d. 2 sec; 48 ft
