1. 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. a. Determine the distance and the displacement the bicyclist has traveled during the entire trip. b. What is her average speed and average velocity for the trip?

Question

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.

Finally, during the third part, she rides for 8.0 minutes at an average speed of 13 m/s towards south. a. Determine the distance and the displacement the bicyclist has traveled during the entire trip. b. What is her average speed and average velocity for the trip? c. Draw the position-time graph d. Draw the velocity-time graph and from this graph calculate the total distance travelled. Match this answer to part "a".
