Manuel is investigating balanced and unbalanced forces. He pushes the same toy truck down a shallow ramp and onto four different surfaces, measuring the distance that the truck travels on each surface. The table shows his results.
Surface Distance Traveled (cm)
bath towel 12
gravel driveway 20
sandbox 8
wooden floor 40
On which surface would it take the longest amount of time for the forces to become balanced?
A.
bath towel
B.
gravel driveway
C.
sandbox
D.
wooden floor
C. sandbox
The surface on which it would take the longest amount of time for the forces to become balanced would be the surface where the truck traveled the shortest distance, which is the sandbox. Since the distance traveled on the sandbox was only 8 cm, it would take longer for the forces to become balanced compared to the other surfaces where the truck traveled further.
