Answer:

887.5 J

Step-by-step explanation:

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

Its formula is :-

KE =
(1)/(2) mv^(2)

  • 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
