Question

A roller coaster moves 200 ft. horizontally, then rises 135 ft. at an angle of 30 degrees above the horizontal. It then travels 135 ft. at an angle of 40 degrees below horizontal. What is its displacement from its starting point at the end of this movement? Use graphical techniques and also find the magnitude and direction.

Answer 1

So the problem ask to calculate the displacement from the starting point to the end of the movement base on the data that has given in the problem. So base on that data, and with my calculation, I came up with an answer of the displacement vector of (420.33, -19.28) and the length of 420.77 ft
