Question

A bus driver heads south with a steady speed of v? = 22.0 m/s for t? = 3.00 min, then makes a right turn and travels at v? = 25.0 m/s for t? = 2.80 min, and then drives northwest at v? = 30.0 m/s for t? = 1.00 min. For this 6.80-min trip, calculate the following. Assume +x is in the eastward direction. (a) total vector displacement (Enter the magnitude in m and the direction in degrees south of west.) magnitude 2720.79 For each straight-line movement, model the car as a particle under constant velocity, and draw a diagram of the displacements, labeling the distances and angles. Let the starting point be the origin of your coordinate system. Use the relationship speed = distance/time to find the distances traveled during each segment. Write the displacement vector, and calculate its magnitude and direction. Don't forget to convert min to s! m direction 19.8 Model the car as a particle under constant velocity, and draw a diagram of the displacements, labeling the distances and angles. Let the starting point be the origin of your coordinate system. Use the relationship speed = distance/time to find the distances traveled during each segment. Write the displacement vector, and calculate its magnitude and direction. Don't forget to convert min to s!° south of west (b) average speed (in m/s) 26.8 Recall that the average speed is the total distance divided by the total time. m/s (c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) magnitude 17.4 The average velocity is the total displacement divided by the total time. Use your result from part (a) for the displacement. m/s direction 19.8 The angle is identical to the angle of the displacement.° south of west
