80. Go When an 81.0-kg adult uses a spiral staircase to climb to the secondfloor of his house, his gravitational potential energy increases by 2.00 × 10³J. By how much does the potential encergy of an 18.0-kg child increasewhen the child climbs a normal staircase to the second floor?

The expression for the potential energy for the adult will be, ∆PE=mghf-h0hf-h0=∆PEadultmadultg
