Extension Questions:
1. If the coefficient of friction between a wheelchair wheel and concrete was 0.4, what is the
maximum angle the ramp could have?
2. Would it make a difference, when determining the maximum angle of a ramp, if you were to use
the coefficient of kinetic friction rather than static friction? Which would be a better choice?
Justify your answer.
3. What is the purpose of a switch-back when driving up the side of a mountain (a switchback is
when the road zig-zags, reversing direction and appearing to go back the way it came, but at a
higher elevation)?
