On a perfect fall day you are hovering at low altitude in a

1. Estimate the buoyant force that air exerts on a man. (To do this, you can estimate his volume by knowing his weight and by assuming that his weight density is about equal to that of water. Assume his weight is 940 N.) answer in N

2. On a perfect fall day, you are hovering at low altitude in a hot-air balloon, accelerated neither upward nor downward. The total weight of the balloon, including its load and the hot air in it, is 17000 N.

(a) What is the weight of the displaced air?

answer in N

(b) What is the volume of the displaced air?

answer in m^3
