Question
Calculate the kinetic energy of a 400 kg horse running 6 m/s
Options:
a) 2400 J
b) 14400 J
c) 4800 J
d) 7200 J
Solution
To calculate the kinetic energy of an object, we can use the formula:
Kinetic Energy = 1/2 * mass * velocity^2
Given that the mass of the horse is 400 kg and its velocity is 6 m/s, we can substitute these values into the formula:
Kinetic Energy = 1/2 * 400 kg * (6 m/s)^2
Simplifying the equation:
Kinetic Energy = 1/2 * 400 kg * 36 m^2/s^2
Kinetic Energy = 200 kg * 36 m^2/s^2
Kinetic Energy = 7200 kg * m^2/s^2
Therefore, the kinetic energy of the horse running at 6 m/s is 7200 J.
So, the correct answer is d) 7200 J.
