You enter the freeway at mile marker 10 and drive north at 50 mph for 1.5 hours until you reach your exit. What is your exit (mile marker) number? (Write the number without units.)

An ant is moving in the negative direction along a meter stick with an average speed of 2.5 cm/s. If you start your timer when the ant is at 65 cm, what is the ant’s position when your timer reads 12 s? (Write the number without units.)

The diagrams plot "trips" taken by four insects by showing the locations of each insect at different times. The dots show where an insect is at a given time and the number next to the dots indicates the time (in seconds) when the insect is at that point. At t= 0, all four insects are moving in straight lines from left to right. Which insect had the highest average speed for the 5-second trip?

• Bug A because it went the greatest distance in the 5 seconds.

• Bug B because it went the greatest distance in the 5 seconds.

• Bug C because it traveled faster at the beginning.

• Bug D because it traveled the greatest distance in any time interval.

The graph represents the relationship between velocity and time for an automobile moving in a straight line. Using any 1-s interval, find the automobile’s acceleration.

• 0 m/s/s

• 1 m/s/s

• 5 m/s/s

• 10 m/s/s

The graph below shows the velocity of an automobile vs. time as the automobile accelerates on a road. An automobile that has a greater acceleration would have a velocity vs. time graph that has a:

• steeper slope.

• slope that is less steep.

• higher velocity at t = 0.

• lower velocity at t = 0.

The velocity vs. time graph for two automobiles is shown. At time t, the automobiles have the same:

• velocity, acceleration, and distance traveled.

• velocity and acceleration.

• velocity only.

• acceleration only.

Look at the speed vs. time graph for Object 1 and Object 2. Which object had the greatest acceleration and why?

• Object 1; it has the greatest change in speed.

• Object 2; it has the fastest final speed.

• Object 1; it has greater constant speed.

• Object 2; it has the highest average speed.

The graph represents the motion of an object. Which of the following statements is true of the object’s acceleration?

• The object travels with constant speed so it doesn’t accelerate.

• The object has constant acceleration from 0 to 2 seconds.

• The object accelerates at 2 seconds.

• The object has increasing acceleration from 0 to 2 seconds and constant acceleration from 2 to 4 seconds.

• The object is at rest so it doesn’t accelerate.
