Below are sample questions representative of the exercises included on this worksheet and related 9.43 Acceleration and Changing Velocity skill assessments:

Problem 1Difficulty: Mastery

North is positive. A car changes velocity from 32 m/s north to 8 m/s south in 8 seconds. What is the average acceleration?

A-5 m/s²

B0 m/s²

C+5 m/s²

D-3 m/s²

Solution & Explanation:With north positive, 8 m/s south is -8 m/s. The change is -8 - 32 = -40 m/s, and -40 / 8 = -5 m/s².

Problem 2Difficulty: Mastery

A roller coaster car moves over the crest of a hill. Its speed before and after the crest is about the same, but its direction changes from upward to downward. What does this show?

AThe car has no velocity at the crest because directions cancel.

BThe car accelerates only if its speed increases after the crest.

CThe car accelerates because the direction of velocity changes.

DThe car has zero acceleration because the speed is about the same.

Solution & Explanation:Velocity includes direction. A change from upward to downward motion is a change in velocity, so acceleration occurs.

Problem 3Difficulty: Mastery

West is positive. Use the table showing velocity +6 m/s at 0 s and -2 m/s at 4 s. What is the average acceleration?

A-1 m/s²

B0 m/s²

C-2 m/s²

D+2 m/s²

Solution & Explanation:The change in velocity is -2 - (+6) = -8 m/s over 4 s, so acceleration is -2 m/s². The sign also shows a direction change relative to west-positive coordinates.
