A 5 kg block is moving with 3 m/s velocity on a frictionless surface. What is its kinetic energy?
Q1. A 5 kg block is moving with 3 m/s velocity on a frictionless surface. What is its kinetic energy?
Answer: 22.5 J
Explanation: Kinetic energy = 1/2 mv² = 1/2 * 5 * 3² = 22.5 J, using the formula for kinetic energy.
