Question SPM.1A.SL.TZ0.5

An object is released from rest in a vacuum at a height $H$ above the Earth’s surface.

As the object falls it passes a point at a height of 0.75$H$ above the surface.

What is $\frac{\mathrm{kinetic} \mathrm{energy} \mathrm{of} \mathrm{the} \mathrm{object} \mathrm{at} \mathrm{a} \mathrm{height} \mathrm{of} 0.75H}{\text{gravitational potential energy of the object at a height of} H}$ ?

A.  $\frac{1}{16}$

B.  $\frac{1}{4}$

C.  $\frac{9}{16}$

D.  $\frac{3}{4}$
