The kinetic energy gained by the ball is equal to the work done on it. Therefore, the ball gains 50J of kinetic energy. Since the question asks for the amount of kinetic energy gained from the player, the correct answer is 0.5J.
Work, energy, and power: Directed by Nicholas Jenkins, Nicole Sweeney. With Shini Somara. Shini discusses the meaning of work, energy, and power in physics.
Work, energy and power are essential concepts in physics. Work is the displacement of an object caused by a force (push or pull). Energy is defined as the ability to perform work. We also get to know about the work done formula and energy formula. 👉 After taking the JEE Main exam,...
