2. A brick becomes dislodged from the top of the Empire State Building (at a height of 1250 feet) and falls to the sidewalk below. s(t) = -16t? + vot + So a. Write the position, velocity, and acceleration functions for the brick's fall. (3 pts) s(t) = v(t) = a(t) = b. How long does it take the brick to hit the sidewalk? Round your answer to the nearest tenth of a foot. (2 pts) c. How fast is the brick traveling when it hits the sidewalk? Round your answer to the nearest tenth of a second. (2 pts) d. What is the acceleration of the brick when it hits the sidewalk? (2 pts)
