The height (in feet) of a ball that is dropped from a 150-ft building is given byh(t) = -16t2 + 150, where t is the time in seconds after the ball is dropped.
Find h(2) and interpret its meaning. Round your answer to the nearest hundredth.
A) h(2) = 3.04 means that after 2 seconds the height of the ball is 3.04 ft.
B) h(2) = 86.00 means that after 2 seconds the height of the ball has dropped by 86.00 ft.
C) h(2) = 86.00 means that after 2 seconds the height of the ball is 86.00 ft.
D) h(2) = 3.04 means that after 2 seconds the height of the ball has dropped by 3.04 ft.

To find h(2), substitute 2 for t in the equation: h(2) = -16(2)^2 + 150 = -16(4) + 150 = -64 + 150 = 86. This means that after 2 seconds, the ball is 86 feet above the ground.
