Come on -- they gave you the formula!
√(19.6h) = 18.5
19.6h = 18.5^2
h = 18.5^2/19.6
Suppose that an object is dropped from a height of h meters and hits the ground with a velocity of v meters per second. Then v= sqrt19.6h. If an object hits the ground with a velocity of 18.5 meters per second, from what height was it dropped?
Carry your intermediate computations to at least four decimal places, and round your answer to the nearest tenth.
