Engineering Mechanics - Dynamics Chapter 12 t 3 3s = r 2 5m = Solution: d π r 1 2 d + r 2 2 + = tt 1 t 2 + t 3 + = v ave d t = v ave 4.285 m s = *Problem 12-72 A car travels east a distance d 1 for time t 1 , then north a distance d 2 for time t 2 and then west a distance d 3 for time t 3 . Determine the total distance traveled and the magnitude of displacement of the car. Also, what is the magnitude of the average velocity and the average speed? Given: d 1 2km = d 2 3km = d 3 4km = t 1 5 min = t 2 8 min = t 3 10 min = Solution: Total Distance Traveled and Displacement
