A bee flies forward at 4.9m/s for 48s , lands on a flower and stays there for 28s , then flies back along its previous route at 5.1m/s for 38s . What is the total displacement of the bee? Round your answer to the nearest thousandth, if necessary.
1 answer:
"Displacement" is the distance and direction between the start-point and the end-point, regardless of the route taken on the way.
From this definition, it's easy to see that the bee's displacement at the end of the adventure is zero.
The bee's distance and average speed could also be calculated using the given information, but are not requested.

Explanation:
To solve this problem we must use the Pythagorean theorem, since the forces are vector quantities, that is, they have magnitude and density. Therefore the Pythagorean theorem is suitable for the solution of this problem.
Resistance reduces the current. If there is more resistance, there is less current.
