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

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