Solution

An object falling freely from the roof of a multistorey building has potential energy and kinetic energy when halfway down the building.
Explanation:

At point A (roof of building), the object is stationary. It will have maximum PE and zero KE.

At point B (halfway), half of PE changes into KE.

At point C (just above ground), the entire PE is converted into KE, hence it will have zero PE and maximum KE.
