a roller coaster moves 85m horizonally, then travels 45m at an angle of 30 degrees above the horizontal. what is its displacement from its starting point?

Question

yahia · Accepted Answer

85 + 45 cos 30 = 124.0 m horizontally 45 sin 30 = 22.5 m vertically The magnitude of the displacement is (124^2 + 22.5^2)

drwls · Answer

85 + 45 cos 30 = 124.0 m horizontally 45 sin 30 = 22.5 m vertically The magnitude of the displacement is sqrt(124^2 + 22.5^2)
