d) Magnetism

Students conducted an investigation where they measured the distance a toy car traveled after rolling down a ramp covered with sandpaper or wax paper. Which of these questions can the students answer by analyzing the results of their investigation?
a) How does changing the height of a ramp affect the distance a toy car rolls?
b) How does changing the surface of a ramp affect the distance a toy car rolls?
c) How does mass affect the distance a toy car moves after rolling down a ramp?
d) How does the design of a toy car affect its movement after rolling down a ramp?

Which two tools below would be most useful in testing how the mass of an object can affect the distance it moves after being pushed?
