MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Velocity and Acceleration A brick becomes dislodged from the top of a building (at a height of 1,260 feet) and falls to the sidewalk below. (Let the position function for a free-falling object be -161- + Vit + hp.) (a) Write the position, velocity, and acceleration functions of the brick. s(t) = V(t) = a(t) = (b) How long does it take the brick to hit the sidewalk? (Round your answer to two decimal places.)
