A few questions that I need urgent help on. Explanations for each question will be greatly appreciated!

1) A honeybee leaves the hive and travels 2 km before returning. Is

the displacement for the trip the same as the distance traveled? If

not, why not?

2) Two buses depart from Chicago, one going to New York and one

to San Francisco. Each bus travels at a speed of 30 m /s. Do they

have equal velocities? Explain.

3) Is the average speed of a vehicle a vector or a scalar quantity?

Provide a reason for your answer.

4) Often, traffic lights are timed so that if you travel at a certain constant

speed, you can avoid all red lights. Discuss how the timing of

the lights is determined, considering that the distance between them

varies from one light to the next.

5) One of the following statements is incorrect. (a) The car traveled

around the track at a constant velocity. (b) The car traveled around

the track at a constant speed. Which statement is incorrect and why?

6) Give an example from your own experience in which the velocity of an object is zero for just an instant of time, but its acceleration is

not zero.

7) At a given instant of time, a car and a truck are traveling side by side

in adjacent lanes of a highway. The car has a greater velocity than the

truck. Does the car necessarily have a greater acceleration? Explain.
