Adaring stunt woman sitting on a tree limb wishes to drop vertically onto a horse gallop ing under the tree. the constant speed of the horse is 12.8 m/s, and the woman is initially 2.23 m above the level of the saddle. how long is she in the air? the acceleration of gravity is 9.8 m/s2 answer in units of s what must be the horizontal distance between the saddle and limb when the woman makes her move? answer in units of m.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
