Final answer:
The kinetic energy of the 1.5 kg ball travelling at a speed of 12 m/s is C) 108 J.
Step-by-step explanation:
The kinetic energy of an object can be calculated using the formula: KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
Given that the mass of the ball is 1.5 kg and its velocity is 12 m/s, we can substitute these values into the formula to calculate the kinetic energy: KE = 0.5 * 1.5 * (12)^2 = 108 J.
Therefore, the kinetic energy of the 1.5 kg ball travelling at a speed of 12 m/s is 108 J.
