A white pool ball of mass 0.60 kg moving at 12 m/s collides with a 0.2 kg red pool ball initially at rest. After the collisions, the white pool ball continues in the same direction with a velocity of 6.0 m/s. Neglecting friction the momentum of the red pool ball after the collision is kg•m/s.

Which of the following are considered noble gases? a. bromine b. neon c. argon d. chlorine

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
