A body of mass 5 kg is moving with a velocity of 4 m/s. What is its kinetic energy?
Q1. A body of mass 5 kg is moving with a velocity of 4 m/s. What is its kinetic energy?
Answer: 40 J
Explanation: Kinetic energy = 0.5 * m * v^2 = 0.5 * 5 kg * (4 m/s)^2 = 40 J. Option B is incorrect due to miscalculation.
