two objects of different mass start from rest, are pulled bythe same magnitude n

Question

two objects of different mass start from rest, are pulled bythe same magnitude net force, and are moved through the samedistance. the work done on object A is 500 J. After the force haspulled each object, object A moves twice as fast as object B.Answer the following questions and show your work. a. how much work is done on object B? b. what is the kinetic energy of object A after beingpulled? c. what is the kinetic energy of object B after beingpulled? d. what is the ratio of the mass of object A to the mass ofobject B? two objects of different mass start from rest, are pulled bythe same magnitude net force, and are moved through the samedistance. the work done on object A is 500 J.

Explanation / Answer

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
