Two billiard balls move toward each other on a table. the mass of the number three ball, m1, is 5 g with a velocity of 3 m/s. the mass of the eight ball, m2, is 6 g with a velocity of 1 m/s. after the balls collide, they bounce off each other. the number three ball moves off with a velocity of 5 m/s. what is the final velocity and direction of the eight ball?

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?
