An object of mass 15 kg is moving with a uniform velocity of 4 m s–1. What is the kinetic energy possessed by the object?

Solution:
Mass of the object, m = 15 kg, velocity
of the object, v = 4 m s^–1, E = 1/2 m v²

k . E = 1 / 2 × 15 kg × 4 m s^–1 × 4 m s^–1
= 120 J
The kinetic energy of the object is 120 J.
