Revolt · Accepted Answer

Part 1: 2.02; Part 2: 2.15; Part 3: 0.13

Question 4

Match the measurement with the proper SI unit. Acceleration: Velocity: Distance:

Revolt · Accepted Answer

Meters per second squared; Selection 1: Meters per second squared; Selection 2: Meters per second; Selection 3: Meters

Question 5

Based on the time measurements in the table, what can be said about the speed of the car on the lower track as compared to the higher track? How can the reasoning for the above answer be best explained? On the higher track, the elapsed time is . Calculate speeds for each track. How much faster was the car on the higher track than the lower track?

Revolt · Accepted Answer

Cars travel faster on the higher track.; Selection 1: Cars travel faster on the higher track.; Selection 2: shorter; Selection 3: 0.56 m/s

Question 6

Read the elapsed time on the stopwatch and answer the questions. In which digit is there the least amount of confidence? How many significant figures does this measurement have?

Revolt · Accepted Answer

Part 1: 7; Part 2: 4

Question 7

Use the graph of distance versus time to complete the sentences. The cars on the higher track travel the cars on the lower track, in the same time. This means that the cars on the higher track have a average speed than those on the lower track. This is demonstrated by the of the higher track line being greater than the slope of the lower track line.

Revolt · Accepted Answer

farther than; Selection 1: farther than; Selection 2: greater; Selection 3: slope

Question 8

Use the graph of speed versus time to answer the questions about acceleration. Which of the cars is speeding up? Which of the cars is slowing down? Which of the cars is maintaining a constant speed?

Revolt · Accepted Answer

Part 1: A; Part 2: C; Part 3: B

Question 9

You are leaving for a party at your cousin’s house in a city that is 150 km away. You will travel at an average rate of 50 km/hr. How long will it take you to arrive? hours If you need to be at the party in 2.5 hours, how fast would you need to drive to get there? km/hr
