Acar travels three-quarters of the way around a circle of radius 20.0 m in a time of 3.0 s at a constant speed. the initial velocity is west and the final velocity is south. (a) find its average velocity for this trip. (b) what is the car's average acceleration during these 3.0 s? (c) explain how a car moving at constant speed has a nonzero average acceleration.

Arace finishes at the same place as it started. the contestants start from rest and cross the finish line running. which one of the following is true about the average speed, the average velocity, and the average acceleration? note that the symbol ≠ means "not equal to". a). average speed = 0 m/s, average velocity ≠ 0 m/s, average acceleration = 0 m/s2 b).average speed ≠ 0 m/s, average velocity = 0 m/s, average acceleration ≠ 0 m/s2 c).average speed = 0 m/s, average velocity = 0 m/s, average acceleration = 0 m/s2 d).average speed ≠ 0 m/s, average velocity = 0 m/s, average acceleration = 0 m/s2 e.)average speed ≠ 0 m/s, average velocity ≠ 0 m/s, average acceleration =0m/s^2

5. if one object has a greater speed than a second object. does the first necessarily have a greater acceleration? explain, using examples. 6. compare the acceleration of a motorcycle that accelerates from 80 km/h to 90 km/h with the acceleration of a bicycle that accelerates from rest to 10 km/h in the same time. 7. can an object have a northward velocity and a southward acceleration? explain. 8. can the velocity of an object be negative when its acceleration is positive? what about vice versa? 9. give an example where both the velocity and accelera- tion are negative. 10. two cars emerge side by side from a tunnel. car a is traveling with a speed of 60 km/h and has an accelera- tion of 40 km/h/min. car b has a speed of 40 km/h and has an acceleration of 60km/h/min. which car is passing the other as they come out of the tunnel? explain your reasoning. 11. can an object be increasing in speed as its acceleration decreases? if so, give an example. if not, explain.
