Answer:
Kolby's kinetic energy is 5000 J.
Explanation:
The speed with which Kolby was running is 10 m/s. The magnitude of speed and velocity are the same.
So we can say that Kolby's velocity = 10 m/s
Mass of Kolby, m = 100 Kg
The kinetic energy of a body is given by the equation,
K.E = (mv²) / 2
∴ Kolby's K.E = (100 × 10²) / 2
= 5000 J
