The kinetic energy of the diver just before he hits the ground is 6860 J.



What is kinetic energy?

Kinetic energy can be defined as the energy of a body due to its motion.

Note: Just before the diver hits the ground, the potential energy is converted into kinetic energy.

Formula:

  • P.E(Potential energy) = K.E(Kinetic energy)
  • K.E = mgh..................... Equation 1

Where:

  • m = mass of the diver
  • h = height of the board
  • g = acceleration due to gravity.

From the question,

Given:

  • m = 70 kg
  • h = 10 m
  • g = acceleration due to gravity.

Substitute these values into equation 1

  • K.E = 70×10×9.8
  • K.E = 6860 J

Hence, The kinetic energy of the diver just before he hits the ground is 6860 J.
