What is the kinetic energy of a toy truck with a mass of 0.75 kg and a velocity of 4 m/s? (Formula: )

Dvinal [7]

Answer: Option (b) is the correct answer.

Explanation:

Kinetic energy is the energy of an object or particle when it is in motion.

Mathematically, Kinetic energy = $\frac{1}{2}mass \times (velocity)^{2}$

It is given that toy truck has mass = 0.75 kg, and velocity = 4 m/s.

Calculate the kinetic energy as follows.

Kinetic energy = $\frac{1}{2}mass \times (velocity)^{2}$

= $\frac{1}{2}0.75 kg \times (4 m/s)^{2}$

= $\frac{1}{2}0.75 kg \times 16 m^{2}/s^{2}$

= $0.75 kg \times 8 m^{2}/s^{2}$

= $6 kg m^{2}/s^{2}$

or, Kinetic energy = 6 joules

Thus, we can conclude that kinetic energy of toy truck is 6 J.
