A scientist was investigating if differences in the frictional work performed on a model car can change
depending on its mass (in grams) and whether the car moves up or down an inclined plane. They decided to
measure the amount of frictional force experienced by the model car and the distance it traveled in meters.
The scientists were able to evaluate the frictional work using the following data.
Mass (g)
Distance (m) Force
Work Done by Friction (J)
car going up the incline
100
39
0.063
2.457
car going down the incline 70
39
0.2309 ?
It is known that the relationship between force and distance determines the work done by friction (W+).
W₁ = fd
Wf work done by friction
f = force
d = distance
Question:
How much work done by friction was exerted on the car as it moved down the inclined plane?
You may use a calculator.
