A 2 kg car is moving at a velocity of 4 m/s. Calculate its kinetic energy.

Solution:

Work is defined as the product of the force applied to an object and the displacement of the object in the direction of the force. Mathematically, work (W) is represented by the equation: A 2 kg car is moving at a velocity of 4 m/s

GPE = m × g × h = 10 kg × 9.8 m/s^2 × 4 m = 392 J A 2 kg car is moving at a velocity of 4 m/s
