Magnitude of average velocity
Name:
magnitude of v = sqrt(7.82 + (-6.6)2) = 10 m/s. 9. A car is driven 1200 m north at 20.0 m/s and then driven 1600 m east at 25.0 m/s. What is the magnitude of the average velocity for this trip? a. 16.1 m/s. b. 22.6 m/s. c. 31.3 m/s. d. 11.3 m/s. e. 62.2 m/s. t = (1200/20) + (1600/25) = 60 + +64 = 124 s. Because the path is a right triangle the
