A brick comes loose from near the top of a building and falls such that its distance s (in feet) from the street (after t seconds) is given by the equation
s(t) = 200 - 16t^2
(see equation in attached file)
How fast is the brick falling after 2 seconds have passed?
Using the differentiation, the solution shows the step-by-step calculation of the speed of the brick falling from a tall building when its motion equation is given.
