A car is making a 40-km trip. It travels the first 20.0 km at 20 km/h and the last 20.0 km at 60 km/h. What is the car's average speed for the entire trip in m/s?

• 8.3 m/s

• 15 m/s

• 20 m/s

• 25 m/s

If you are driving 82 km/h along a straight road and you look to the side for 4.0 s, how far do you travel during this inattentive period?

• 91.1 meters

• 100 meters

• 82 meters

• 110 meters

Suppose that an object travels from one point in space to another. Make a comparison between the displacement and the distance traveled.

• The displacement is always equal to the distance traveled.

• The displacement can be either greater than, smaller than, or equal to the distance traveled.

• The displacement is either less than or equal to the distance traveled.

• If the displacement is equal to zero, then the distance traveled will also equal zero.

Suppose that an object is moving with a constant velocity. Make a statement concerning its acceleration.

• The acceleration must be a constant non-zero value.

• The acceleration must be equal to zero.

• The acceleration must be constantly increasing.

• The acceleration must be constantly decreasing.
