A car travels 75 meters to the right with a constant velocity of 7 m/s. How long did it take to do this? AmNA 11. During the first 35 s a truck traveled at constant velocity of 20 m/s. What was the truck's displacement? 12. A car accelerates from rest to a velocity of 35 m/s in 5 seconds. What is the acceleration of the car? / milt's 13. An object is traveling at a constant velocity of 10 m/s when it experiences a constant acceleration of 2.5 m/s for a time of 5 s. What will its velocity be after that acceleration? 14. A car is driving at a velocity of 30 m/s. If its brakes can supply an acceleration of -6.0 m/s', how long will it take to bring the car to a stop? 0 / 30 Use the position vs time graph showing a person's motion to answer questions 15 - 17. 15.
