Question

The mass of a beetle is 0.000004kg. If a beetle's center of mass rises 0.75 mm while it is pushing against the floor and then continues to travel up to a height of 250 mm above the floor, what is the magnitude of the force exerted by the floor on the beetle?

Answer 1

work in = increase in potential energy

F (.75/1000) = m g h = 4*10^-6 * 9.81 * .25

Answer 2

F=mgh
F=(0.000004kg)(9.8)(250 power of(-3) - 0.75power of(-3))=answ

F=answ/(0.75power of(-3))
