Two boys are throwing a baseball back and forth. The ball is 4 ft above the ground when it leaves one child’s hand with an upward velocity of 36 ft/s. If acceleration due to gravity is –16 ft/s2, how high above the ground is the ball 2 s after it is thrown?
h(t) = at2 + vt + h0
A 12 ft
B 20 ft
C 76 ft
D 116 ft
