answer) here initial velocity is
vo=-65j ( pointing south which is negative y direction)
vf=-80i( pointing west which is negative x direction)
so v=vf-vo=-80i+65j
magnitude=(-802)+652=103 m/s
so the answer is 103 m/s or 103.1m/s
and angle =tan-1(65/-80)=-39o
so angle=-39o or -39.1o.( if the answer comes out wrong try 39o or 39.1o and omit the negative sign)
