a. Any Height

b. Any floor other than the ground floor.

Explanation:

For a fallen object

PE (potential Energy) = KE (Kinetic Energy)

therefore

In this case only a change in form of energy was witnessed.

According to law of conservation of mass, " states that mass can neither be created nor destroyed"

Mass is conserved over time despite change in form, Mass quantity is neither added nor removed.

Since all pumpkin gore was collected and weighed.

At any known height

M_b (mass before drop) = M_a (mass after drop)
