A car undergoes a displacement of 1200m @ 90degrees, follow by another displacement of 900m @ 0degress.
Calculate the average speed for the whole trip and the time to return to the starting point in the shortest possible distance at 20.0m/s
Avg speed would be total displacement/total time
2100m/210s=10.0 m/s, which is not right, it should be 12.7m/s and I don't know how to arrive at that figure?
The time for the second equation should be 75.0s. How do I get there?
If the total time that I have for the whole trip is 210s? Is that even the correct time?
