Question
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 500 J. After the force has pulled each object, object A moves twice as fast as object B. Answer the following questions and show your work.

**Question 3A: How much work is done on object B?**

- The work that is done on object B = 500 J

**Question 3B: What is the kinetic energy of object A after being pulled?**

- The kinetic energy of object A after being pulled is 500 J

**Question 3C: What is the kinetic energy of object B after being pulled?**

- The kinetic energy of object B after being pulled is 500 J

**Question 3D: What is the ratio of the mass of object A to the mass of object B?**

- (The correct answer is not provided in the image, but based on the information given: since object A moves twice as fast as object B and kinetic energy is proportional to the square of velocity, object A must have one-fourth the mass of object B for the kinetic energies to be equal. Therefore, the ratio of the mass of object A to that of object B is 1:4.)
