On the way to class, you walk north and then west such that your resultant displacement is 290 m in a direction 250 west of north. Your average velocity is 2.0 m/s in the same direction as the displacement. Calculate (a) your walking time and (b) your average speed.
Direction = 25.0o West of north?
a. D = 290m[25.0o]
t = D/V = 290[25.0]/2[25o] = 145 s.
b. r = D/t = 290m/145s = 2m/s.
