What is the kinetic energy of a 54 kg person, diving into a pool at a speed of 30 m/s?


24,300 J

  • Q: What is the formula for kinetic energy? A: The formula for kinetic energy is KE = 1/2 mv^2, where KE is kinetic energy, m is mass and v is velocity.
  • Q: What is the mass of the person? A: The mass of the person is 54kg.
  • Q: What is the velocity of the person diving? A: The velocity of the person diving is 30m/s.
  • Substitute the values into the formula for kinetic energy. KE = 1/2 x 54kg x (30m/s)^2 = 24,300 J
