An object is thrown horizontally from the open window of a building. If the initial speed of the object is 20 m/s and it hits the ground 2.0 s later, from what height was it thrown? (Neglect air resistance and assume the ground is level.) 

Sagot :

The answer is 40 meters. Formula? d=vt, then, d=(20)(2), is equal to 40 meters.
