Amail carrier parks her postal truck and delivers packages. to do so, she walks east at a speed of 0.80 m/s for 4.0 min, then north at a speed of 0.50 m/s for 5.5 min, and finally west at a speed of 1.1 m/s for 2.8 min. define east as +x and north as +y. (a) write unit-vector velocities for each of the legs of her journey. (b) find unit-vector displacements for each of the legs of her journey. (c) find her net displacement from the postal truck after her journey is complete.

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
