Question

Two objects of differnt mass start from rest, are pulled bythe same magnitude net force, and are moved through the samedistance.The work done on object A is 500J. After the force haspulled each object, object A moves twice as fast as object B. How much work is done on object B? What is the kinetic enerdy of object A after beingpulled? What is the kinetic energy of object B after beingpulled? what is he ratio of the mass of object A to the mass of objectB?

Explanation / Answer

as the force applied and distance moved are same the work done on the object B is 500 J we have     work done = change in the kineticenergy so the  the kinetic enerdy of object Aafter being pulled =500 J      the kinetic enerdy ofobject B after being pulled=500 J let the velocity of the object B is V thenthe velocity of the object A is 2V as the kinetic energies of the two objects areequal                                  1/2 mB V2 = 1/2 mA (2V)2                              mA / mB = 1/4                              mA / mB = 1/4
