You are presently taking a weather observation. the sky is full of wispy cirrus clouds estimated to be about 10 km overhead. if a warm front is approaching from the south, about how far is it (assuming a slope of 1: 200)? enter only the numeric value of the distance.

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.
