Answer :

The potential energy of the body at height 100 m is 98 J

What is potential energy?

This is the energy possessed by a body by virtue of his position. Mathematically, it can be expressed as

PE = mgh

Whare

  • PE is the potential energy
  • m is the mass
  • g is acceleration due to gravity
  • h is the height

How to determine the potential energy

From the question given above, the following data were obtained:

  • Mass (m) = 100 g = 100 / 1000 = 0.1 kg
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Height (h) = 100 m
  • Potential energy (PE) =?

PE = mgh

PE = 0.1 × 9.8 × 100

PE = 98 J

Thus, the potential energy at height 100 m is 98 J
