11250J
Explanation:
Given parameters:
Mass of the person = 100kg
Velocity = 15m/s
Unknown:
Kinetic energy = ?
Solution:
The kinetic energy of a body is energy due to the motion of the body.
Kinetic energy = 
m v²
m is the mass of the body
v is the velocity
Substituting the parameters:
K. E = x 100 x 15² = 11250J
