MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A cab driver heads south with a steady speed of V1 = 24.0 m/s for {I = 3.00 min, then makes a right turn and travels at v2 = 25.0 m/s for I2 = 2.40 min, and then drives northwest at v3 = 30.0 m/s for IS : 1.00 min. For this 6.407min trip, calculate the following. Assume +x is in the eastward direction. (a) total vector displacement (Enter the magnitude in rn and the direction in degrees south of west.) magnitude 3834 226 x For each straightaline 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 pornt 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 127 37 x 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 he 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!D south of west (b) average speed (in rn/s) 25 3125 J m/s (c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) magnitude 9985 X The average velocity is the total displacement divided by the total time. Use your result from part (a) for the displacement. m/s direction i2? 37 x The angle is identical to the angle of the displacement.D south of west Need Heirv7 4.
