What is the kinetic energy of a 15 kg dog that is running at a speed of 8.7 m/s (about 19 mi/h)?
(12)(15)(8.7)^2
To determine the kinetic energy of an object, you need to use the formula for kinetic energy:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
In this case, the mass of the dog is given as 15 kg, and the velocity is given as 8.7 m/s.
1. Square the velocity: 8.7^2 = 75.69 m/s^2.
2. Multiply the squared velocity by half of the mass: 0.5 * 15 kg * 75.69 m/s^2 = 5680.35 joules (J).
So, the kinetic energy of the 15 kg dog running at a speed of 8.7 m/s is approximately 5680.35 joules.
