Mr. mcniven is hiking in a florida state park. if mcniven hikes 15 kilometers in a westerly direction, then turns 90 degrees and walks 30 kilometers directly south, determine the magnitude and direction mcniven is from his starting point.

33.5 km at south of west

Explanation:

To solve the problem, we take the following convention:

- West is positive x-direction

- South is positive y-direction

Using this convention, we can describe the two parts of the motion as follows:

1) 15 km west: the components of this part of the motion are

2) 30 km south: the components of this part of the motion are

Therefore, the components of the net displacement are

So, the magntidue of the net displacement is

while the direction is:

south of west.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
