Answer:
18.75 joules.
Step-by-step explanation:
Kinetic energy = 0.5 * mass * velocity^2
mass of the object is 1.5 kg and its velocity is 5 m/s, substitute these values into the formula:
Kinetic energy = 0.5 * 1.5 kg * (5 m/s)^2
Simplifying
Kinetic energy = 0.5 * 1.5 kg * 25 m^2/s^2
Kinetic energy = 18.75 J
the kinetic energy of the object is 18.75 joules.
