Answer:

4000 J

Step-by-step explanation:

The energy possessed by virtue of motion of the body is called its kinetic energy.

When a body is in motion , it has kinetic energy.

Mass of the object, m = 80 kg

velocity of the object, v = 10 m/s

The formula for the kinetic energy is given by


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

K = 0.5 x 80 x 10 x 10

K = 4000 J

Thus, the kinetic energy of the object is 4000 J.
