A helicopter starts from rest at point A and travels along the straight-line path with a constant
Question:
A helicopter starts from rest at point A and travels along the straight-line path with a constant acceleration a. If the speed v = 28 m/s when the altitude of the helicopter is h = 40 m, determine the values of r˙, r¨, θ˙ , and θ¨ as measured by the tracking device at O. At this instant, θ = 40°, and the distance d = 160 m. Neglect the small height of the tracking device above the ground.
