Which dog has the most kinetic energy

15 kg going 3 m/s

8 kg going 4 m/s

12 kg going 5 m/s

10 kg going 6 m/s

The formula to find the kinetic energy is:

Ek = 1/2 * m * v^2

1. Ek = 1/2*15*3^2

= 67.5 J

2. Ek = 1/2*8*4^2

=64 J

3. Ek = 1/2*12*5^2

= 150 J

4. Ek = 1/2*10*6^2

= 180 J

So the fourth dog has the most kinetic energy.
