Imagine the running deer has a mass of 100 kg and is running at a speed of 8 m/s. What is the deer’s kinetic energy, in joules?

3200 joules.

Explanation:

Mass of deer = 100kg

Speed of running deer = 8 m/s

Kinetic energy = ?

Kinetic energy is the energy possessed by a moving body (deer). It is measured in joules.

Thus, Kinetic energy = 1/2 x (Mass x velocity^2)

K.E = 1/2 x (100kg x (8m/s)^2)

K.E = 1/2 x (100 x 64)

= 0.5 x 6400

= 3200 joules

Thus, the kinetic energy of the running deer is 3200 joules.
