Question

A cat, walking along the window ledge of a New York apartment, knocks off a flower pot, which falls to the street 210 feet below. How fast is the flower pot traveling when it hits the street? (Give your answer in ft/s and in mi/hr, given that the acceleration due to gravity is 32 ft/s^2 and 1 ft/s = 15/22 mi/hr.)

Answer 1

you know that s = 1/2 at^2 and v = at, so v = √(2as)
v = √(2*32*210) ft/s
I expect you can convert that to mi/hr.
