A body is moving with a velocity of 10 m/s. If its kinetic energy is 50 J, what is its mass?
Q1. A body is moving with a velocity of 10 m/s. If its kinetic energy is 50 J, what is its mass?
Answer: 1 kg
Explanation: Kinetic energy = 1/2 mv², 50 = 1/2 * m * 10², m = 1 kg, using the formula for kinetic energy.
