What is the average velocity of a cat chasing a mouse that traveled 2,500 meters East in 40 seconds? What was the final velocity of the mouse if it started from rest with a acceleration of 2.5 m/s^2 during the same time period above? Show equations and work.

What is the answer for this. the correct answer only

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.
