Hi, I have a two questions that I am trying to figure out. If you can help me, that would be great. 1. A roller coaster moves 200 ft horizontally and then rises 135 ft at an angle of 30 above the horizontal. Next, it travels 135 ft at an angle of 40 below the horizontal. Find the roller coaster's displacement from its starting point to the end of this movement. 2. Two points are given in polar coordinates by (r, angle) = (2.00m, 50.0 angle), 2nd one is (5.00, -50 angle), respectively. What is the distance between them? Thank you ahead of time.
