    Q:

    		 A box sits atop a frictionless ramp and then from rest, slides down it, achieving some speed at the very bottom (before it hits the floor). For that same box to achieve a speed (at the bottom of the ramp) twice as fast as the original, how much taller should a new ramp be?

    		 

    A

    		 The new ramp should be the same height as the original, but with a more gradual slope

    B

    		 The new ramp should be twice as high as the original

    C

    		 The new ramp should be three times higher than the original

    D

    		 The new ramp should be four times higher than the original
