a race car travels northward on a straight level track at a contant speed traveling 0.750 km in 20.0s. the return trip over the same track is madein 25.os
great. Now is there a question here?
15000ms
To find the average speed of the race car, we need to divide the total distance traveled by the total time taken.
For the northward trip:
Distance traveled = 0.750 km
Time taken = 20.0 s
For the return trip:
Distance traveled = 0.750 km (since it is the same track)
Time taken = 25.0 s
Now, we can calculate the average speed for each trip using the formula:
Average Speed = Distance / Time
For the northward trip:
Average Speed = 0.750 km / 20.0 s = 0.0375 km/s
For the return trip:
Average Speed = 0.750 km / 25.0 s = 0.03 km/s
So, the average speed of the race car on the northward trip is 0.0375 km/s, and on the return trip is 0.03 km/s.
