1. The problem statement, all variables and given/known data I just did this question, and I just want to make sure I did it right... Can u run through it and notify me of any errors? 2. Relevant equations Here is the question: http://i299.photobucket.com/albums/mm286/lanvin12/333-1.jpg 3. The attempt at a solution this is what I did... V(x) = V(bx) - V(ax) = [ (4.4m/s) sin 31° ] - [ (7.8m/s) sin 25° ] = 1.030262m/s V(y) = V(by) + V(ay) = [ (4.4m/s) cos 31° ] - [ (7.8m/s) cos 25° ] = 10.840736 m/s V² = V(x)² + V(y)² = 10.8² + 1.03² + 118.5 V = √118.5 = 10.88 A = V / t = 10.88 / 8.55 = 1.28m/s² tan theta = 10.84 / 1.030 = 10522 theta = tan^(-1) 10.52230 = 84.57° therefore, the bird's acceleration was 1.3 m/s² [85° S of E] is that right? Was I supposed to use TOA? Significant digits ok? Any mistakes...?
