A student drops an object out the window of the top floor of a high-rise dormitory.
(a) Neglecting air resistance, how fast is the object traveling when it strikes the ground at the end of 3.0 s? First use standard British units, and then express the speed in mi/h for a familiar comparison. Can things dropped from high places be dangerous to people below?
(b) How far, in meters, does the object fall during the 3.0 s? Comment on how many floors the dormitory probably has.
