Question

rolling down a ramp
changing height
a student set up an investigation to see how far a toy car would roll when let go of at different heights on a ramp. they made the line graph below.
how far will the car roll?
distance rolled (cm)
height dropped from (cm)
look at the graph. which statement is true?
the car rolls farther when it is dropped from a lower height.
the car rolls a shorter distance when it is dropped from a higher height.
the car rolls farther when it is dropped from a higher height.

Explanation:

By analyzing the line graph: when the height dropped from is 5 cm, the car rolls 15 cm; at 10 cm height, it rolls 20 cm; at 15 cm height, it rolls 25 cm. This shows as the drop height increases, the rolling distance increases.

Answer:

The car rolls farther when it is dropped from a higher height.
