The following free-body diagram represents a toboggan on a hill. What acceleration would you expect, and why?
- Acceleration down the hill; the force due to being pushed, together with the downhill component of gravity, overcomes the opposing force of friction.
- Acceleration down the hill; friction is less than the opposing component of force due to gravity.
- No movement; friction is greater than the force due to being pushed.
- It depends on how strong the force due to friction is.
