calculate the kinetic energy of a 71 kg man running at 5 m/s

Sagot :

Answer:

887.5 J

Explanation:

Kinetic energy is the energy gained by a body due to its motion.

Its formula is :-

KE = [tex]\frac{1}{2} mv^{2}[/tex]

  • m = mass
  • v = velocity

Values we are given :

  • m = 71 kg
  • v = 5 m/s

Substituting :

  • KE = 1/2 x 71 x 5²
  • KE = 35.5 x 25
  • KE = 887.5 J
