A Physics Student Standing on the Edge of a Cliff

question 18

Multiple Choice

A physics student standing on the edge of a cliff throws a stone vertically downward with an initial speed of 10.0 m/s. The instant before the stone hits the ground below, it is traveling at a speed of 30.0 m/s. If the physics student were to throw the rock horizontally outward from the cliff instead, with the same initial speed of 10.0 m/s, what is the magnitude of the velocity of the stone just before it hits the ground?

• A)10.0 m/s
• B)20.0 m/s
• C)30.0 m/s
• D)40.0 m/s
• E)The height of the cliff must be specified to answer this question.
