What is the kinetic energy of a 4-kg toy car moving at a velocity of 8 m/s? O 32J
64 J
O
128 J
256 J

Explanation:

The kinetic energy of an object can be found by using the formula

m is the mass

v is the velocity

From the question we have

We have the final answer as

Hope this helps you

Mass of toy the car = 4 kg

Velocity of toy the car = 8 m/s

Kinetic energy of an object is the energy that it possesses due to its motion.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity.

Formula of Kinetic energy:

KE → Kinetic energy of the Object (J)

m → Mass of the Object (kg)

v → Speed of the Object (m/s)

By substituting values in the formula, we get:

Kinetic energy of the toy car = 128 J
