Question

If F and 3 F be the forces applied to the two different bodies of equal masses, then the ratio of the kinetic energy possessed by the two bodies will be 9 : 16. What will be the ratio of the power generated by the two bodies on which the force F and 3 F is applied? in work and energy​

Answer 1

Answer: It is an advanced answer so an explanation given below

Explanation:y Newton’s second law of motion.F→=dp→dt. If the force acts for a very short duration dtdt, say, then the change in momentum .dp→=dp→dtdt=F→dt, from the previous equation. Since the two objects are being acted by the same force for the same amount of time, from the above equation, the change in momentum is the same for both objects. If the momenta of the objects were equal before the application of the force, then the momenta of the objects are equal after the force is applied and then withdrawn.
