Marisol has two toy cars attached to two elastic strings of the same length and material as shown below.

• Does the amount of force to pull each car affect the mass?

• Does the mass affect the distance each toy car travels?

• Does the thickness of the string affect the total force used?

• Does the force applied affect the length of the string?

Which of the following experiments would demonstrate how the mass of objects when pushed the same distance affects the total time traveled?

• Observe how far objects of different masses will travel when they are pushed by different amounts of force.

• Observe how much time it takes for objects of different masses to travel the same distance when pushed by different forces.

• Observe how far objects of the same mass will travel when they are pushed by different amounts of force.

• Observe how much time it takes for objects of different masses to travel the same distance when pushed by the same amount of force.

What should the student do to improve this experiment?

• Use the blocks of equal mass on the four pieces of elastic

• Use blocks with enough mass to cause the four pieces of elastic to break

• Use more than four pieces of elastic and four blocks

• Use four pieces of elastic with different lengths but the same width
