2 A block of mass M is hanging over a smooth and light pulley through a light string The other end of the string is pulled by a constant force F The kinetic energy of the block increases by 20 J in 1s 1 the tension in the string is Mg 2 the tension in the string is F 3 the work done by the tension on the block is 20 J in the above 1 s 4 the work done by the force of gravity is 20 J in the above 1s Fin distance x If the stopping force is 4F
