1. **State the problem:** We want to find how long it takes toy cars to travel 60 centimeters to the end of the table. 2. **Analyze the options given:** - The time taken depends on forces acting on the cars, not just mass. - Gravity force is the same for both cars on a horizontal table, so it does not affect time differently. - Force pulling the cars is not necessarily the same; friction can differ. - Different friction forces can cause different times. 3. **Physics principle:** The time to travel a distance $d$ under constant acceleration $a$ starting from rest is given by $$d = \frac{1}{2} a t^2 \implies t = \sqrt{\frac{2d}{a}}$$ 4. **Friction and acceleration:** The net acceleration depends on the net force, which is affected by friction. Different friction means different acceleration and thus different times. 5. **Conclusion:** The correct reasoning is: "The cars will take different amounts of time because the force of friction is different between them." Final answer: The cars take different times due to different friction forces affecting their acceleration and travel time.
