Answer :
Final answer:
The kinetic energy of a 150 kg object moving at a speed of 15 m/s is calculated to be 16875 J, making the correct answer A) 16875 J.
Explanation:
The formula for calculating kinetic energy is KE = 0.5 * mass * velocity^2.
Using this formula, we can calculate the kinetic energy of the 150 kg object that is moving with a speed of 15 m/s as follows:
KE = 0.5 * 150 kg * (15 m/s)^2
Simplifying the equation:
KE = 0.5 * 150 kg * 225 m^2/s^2
KE = 16875 J
Therefore, the kinetic energy of the object is 16875 J (option A).
