A bicyclist makes a trip that consists of three parts. During the first part, she rides for 22 minutes at an average speed of 7.2 m/s in the direction of North. During the second part, she rides for 36 minutes at an average speed of 5.1 m/s again in the North direction. Finally, during the third part, she rides for 8.0 minutes at an average speed of 13 m/s towards south. Determine the distance and the displacement the bicyclist has traveled during the entire trip. What is her average speed and average velocity for the trip? Draw the position-time graph Draw the velocity-time graph and from this graph calculate the total distance travelled. Match this answer to part “a”.
