8. A car travels 21 miles m 20 minutes e. How many Iwans did the car spend traveling? b. What was the average velocity of the car in miles per hour during its trip? c. After reaching its destination, suppose the car travels an additional 100 miles over 2.5 hours. Find the average velocity of the car in mph over this second trip. d. Find the average velocity of the car in moh over the combined legs of the trip. e. Drew and label a position va. time graph showing the trip the car made. Include lines for each leg of the trip as well as the combined journey. . Compare the slopes of each line. Are any of the average velocities the same? Should they be? 7. The driver of a sports car traveling at 10.0 m/s steps down hard on the accelerator for 5.0 s and the velocity increases to 30.0 m/s. What was the average acceleration of the car during the 5.0 s time interval? 8. A swan on a lake gets airbome by flapping its wings and running on top of the water. If the swan must reach a velocity of 6.00 m/s to take off and it accelerates from rest at a constant rate of 0.350 m/s , how far will it travel before becoming airborne? 9. A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4:00 m/s and her takeoff point is a m above the pool, How long are her feet in the air? 10. A bullet in a gun is accelerated from the finng chamber to the end of the barrel at an average rate of 6:30-10 m/s? for 8. 10- 10t's. What is the bullet's final velocity when it leaves the barrel, commonly known as the muzzle velocity
