Initially, a swift-moving hawk is moving due west (in the -x direction) with a speed of 60 m/s; 5.0 s later it is moving due north (in the +y direction) with a speed of 25 m/s. (a) What are the magnitude and direction of v(ave) during this 5.0 s interval? What is the direction in degrees from the +x-axis? (b) What are the magnitude and direction of a(ave) during this 5.0 s interval? What is the direction in degrees from the +x-axis? I have already set up this question so that Vi=-60m/s and Vf=25m/s to give the velocity vector V=25i+60j. This yields a correct magnitude of 65m/s. The average acceleration was set up similarly except each component divided by 5(time interval) to give a vector a=5i+12j. The real issue now is finding the angle from the +x-axis. I tried Tan-1(60/25) plus 180 but no dice. What am I doing wrong?
