A batter checks her swing as a 0.15-kg baseball crosses home plate outside the strike zone. If the separation between the batter and the ball is 0.77 m and the gravitational force exerted on the batter by the ball is 1.1 X 10-9 N, what is the mass of the batter?

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.
