QUESTION 1 A truck, that is initially at rest, begins to move along level ground due south with a uniform acceleration of 2.0 m/s? until it reaches a speed of 18 m/s. At that point, the driver releases the accelerator so that the truck coasts at a constant speed due south for a time of 6.0 s. What is the average speed of the truck for the entire trip? a. 12.6 m/s O b. 22.2 m/s Oc. 17.4 m/s O d. 19.8 m/s e. 15 m/s
