Question

In each of these, the x- and y-components of a vector aregiven. Find the magnitude and direction of the vector. (d) ax = 2.3 m/s2 , ay = 6.5 m/s2.   I did mag F = (2.3m/s2)2 + (6.5 m/s2)2 =47.54 = 6.89 m/s2 = Fmag. tan = opp/adj = tan -1 (opp/adj) = tan -1 (6.5 m/s2 / 2.3 m/s2) = 70.5 deg CCW from the + x-axis Book says ...... F mag = 2.3 m/s2 at 1.6 deg CCWfrom +x-axis. Is book right? If so, how to solve correctly? thanks, Paul In each of these, the x- and y-components of a vector aregiven.
