Physics

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. The work done on object A is 500J. After the force pulled each object, object A moves twice as fast as object B. Answer the following:

a.) How much work is done on object B

b.) What is the kinetic energy of object A after being pulled?

c.) What is the kinetic energy of object B after being pulled?

d.) What is the ratio of the mass of object A to the mass of object B?
