• because he pushed the cars at the same time

• because he pushed the cars at different times

• . because he applied different forces to the two cars

• because he applied the same force to each of the two cars

Two objects of different mass are being pushed with an equal amount of force at the same time. Which will most likely occur?

• The object with a greater mass will move farther than the object with less mass.
