Final answer:
To calculate the time and average acceleration for the kayak team from the 1992 Summer Olympics, one would use distance and average speed to find time, and the change in velocity over time for acceleration. However, the provided answers do not match calculated results, implying an issue with the available options.
Step-by-step explanation:
The question involves the calculation of time and average acceleration for a German four-man kayak team in the 1992 Summer Olympics as it increased its speed from 0.0 m/s to 6.0 m/s over a distance of 150 m.
Part A: Time Calculation
To find the time taken to cover 150 m at an average speed of 3.0 m/s, we use the formula:
time = distance / average speed
time = 150 m / 3.0 m/s = 50 seconds
Part B: Average Acceleration Calculation
To find the average acceleration, we use the formula:
average acceleration = (final velocity - initial velocity) / time taken
average acceleration = (6.0 m/s - 0.0 m/s) / 50 s = 0.12 m/s2
Conclusion
However, none of the answer choices match our calculated results. Therefore, we must assume there is either an error in the provided choices or additional information is needed to match the conditions of the question.
