Abusy chipmunk runs back and forth along a straight line of acorns that has been set out between its burrow and a nearby tree. at some instant, it moves with a velocity of â’1.47 m/s. then, 2.07 s later, it moves with a velocity of 1.73 m/s. what is the chipmunk's average acceleration during the 2.07 s time interval?

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.
