1. Here a stone at rest is suspended by a string. (a) Draw force vectors for all the forces that act on the stone. (b) Should your vectors have a zero resultant? (c) Why or why not?

2. Here the same stone is being accelerated vertically upward. (a) Draw force vectors to some suitable scale showing the relative forces acting on the stone. (b) Which is the longer vector, and why?
