Please help, have no idea on how to solve it. Joel is pulling a sled up a hill at an angle of 30 degrees above the horizontal for 5 meters. He turns 180 degrees to his right, and pulls for an additional 6 meters. What is the resultant vector of his motion?

-1m

Explanation:

I'm assuming it means that you treat the distance travelled as a displacement vector (distance of a particular direction and magnitude)

If he turns 180 degrees, he is travelling in the exact opposite direction to his original direction of travel. Therefore if he was travelling 5m in one direction, then afer his turn he travels 6m in the exact opposite direction. Opposite directions can be interpreted as the negative of the original direction.

Resultant vectors are the sum of vectors.

The sum of vectors is equal to 5m + - 6m = -1m

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
