Neylin engineered (drove) a horse train from miami and traveled toward new york. 14
hours later matt drove from miami in a diesel train traveling at 45 km/h in an effort to
catch up to the neylin's train. after traveling for four hours the diesel train finally caught
up. what was the cattle train's average speed?

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.
