Question 1: Calculate the distance traveled when a vehicle moves at a constant speed of 60 km/h for 2 hours.

Answer: 120

Question 2: A car accelerates from 0 to 60 km/h in 10 seconds. If the acceleration is uniform, what is the average velocity during this period? (Convert km/h to m/s if necessary)

Answer: 8.33

Question 3: A velocity-time graph shows a constant velocity of 40 m/s for 5 seconds, then a decrease to 0 m/s in 3 seconds. Calculate the total distance traveled during the entire period.

Answer: 220

Question 4: Identify the common mistake made when calculating distance as just velocity multiplied by total time without considering changes in velocity shown on a graph.

Answer: Ignoring variations in velocity and assuming constant speed

Question 5: A velocity-time graph shows the velocity increasing linearly from 0 to 50 m/s over 10 seconds. What is the total distance traveled during this time?

Answer: 250

Question 6: Construct a velocity-time graph for a vehicle that travels at 20 m/s for 4 seconds, then decelerates uniformly to 0 m/s over the next 6 seconds. Calculate the total distance covered.

Answer: 80

Question 7: A student calculates the distance traveled as 50 km/h × 4 hours = 200 km, but their velocity-time graph shows an initial speed of 60 km/h and then a reduction. Explain the error and how to correctly determine the distance.

Answer: They ignored changes in velocity; should calculate area under the graph for each segment

Question 8: A velocity-time graph shows a steady velocity of 30 m/s for 8 seconds. A mistake is made by calculating distance as 30 m/s × 8 seconds = 240 m. Is this correct? Why or why not?

Answer: Yes, because velocity is constant; distance = velocity × time

Question 9: A velocity-time graph shows a decrease from 20 m/s to 0 m/s over 5 seconds. Construct the graph and find the total distance traveled.

Answer: 50

Question 10: Identify and correct the mistake in this student's reasoning: They added the areas of the velocity segments directly to find total distance without considering the shape of the graph.

Answer: They need to calculate the actual areas (considering shape); simply adding segments may ignore the correct area calculation
