1. The problem statement, all variables and given/known data A bird take 8.5 seconds to travel from point A to point B. At point A, the velocity of the bird is 4.4m/s [31 degrees S of E], and at point B, the bird's velocity is 7.8m/s [25 degrees N of E]. What is the average rate of acceleration? 2. Relevant equations A=V/T, Ax-Vx/T, Ay=Vy/t, Tan(angle)=Ay/Ax, V=D/t, Viy=Vi sin(angle i), Vix=Vi Cos(angle i), repeat vi(x), vi(y) for vf variables. 3. The attempt at a solution A=0.4 m/s^ The part i don't understand is the bearing. What i DO understand is that to get the final bearing you use the Tan(angle)=Ay/Ax equation. I can get both initial velocity bearings for x and y, but I am having problems figuring out how to get the final velocity's x and y. I know that #1, the difference in degree's between point A and point B is 56 degrees. I also know that when making a right angle triangle with the points, the angle of point b is 59 degrees. My problem is finding the bearing of acceleration. I've been stumped on this one for a day or 2 now, and my math skills definitely need some practice.
