A 10 kg block is moving with 2 m/s velocity on a frictionless surface. What is its kinetic energy?
Q1. A 10 kg block is moving with 2 m/s velocity on a frictionless surface. What is its kinetic energy?
Answer: 20 J
Explanation: Kinetic energy = 1/2 mv² = 1/2 * 10 * 2² = 20 J, using the formula for kinetic energy.
