You are tasked to design a new car for the XYZ motor company. Your manager tells you that the vehicle must weigh less than 2,000 lbs. and be shorter than 13 feet in length. The engine and the seats inside have already been designed by other engineers. Given these instructions, what is one design constraint that you must follow?

• The car must have a sunroof.

• The car must weigh less than 2,000 lbs.

• The car must be painted red.

• The car must have leather seats.

Will any two objects traveling at the same speed have the same kinetic energy? Why or why not?

• Yes, because speed is the only factor in kinetic energy.

• No, because kinetic energy also depends on mass.

• Yes, because all objects have the same mass.

• No, because kinetic energy depends on color.

Would changing only the rolling resistance of a vehicle change the amount of potential energy it has at the top of the ramp?

• Yes, because rolling resistance affects height.

• No, because potential energy depends only on height and mass.

• Yes, because rolling resistance affects mass.

• No, because potential energy depends on speed.
