In the figure, a rescue plane flies at 198 km/h (= 55.0 m/s) and constant height h = 500 m toward a point directly over a victim, where a rescue capsule is to land. (a) What should be the angle \(\phi\) of the pilot's line of sight to the victim when the capsule release is made? (b) As the capsule reaches the water, what is its velocity? (03小題)

(a)\(\phi=\)_____ degree
分數= 1  可嘗試次數= 5  誤差=0.2

(b)the velocity \(\vec{v}=v_x \hat{i} + v_y \hat{j}\),
(b1) \(v_x\)=____ m/s
分數= 1  可嘗試次數= 5  誤差=0.2

07

(b2) \(v_y\)=____ m/s
分數= 1  可嘗試次數= 5  誤差=0.2
