Question

(b) at" 30.9218m? e-1318.5 , Graded Hw#1 An airplane flying at v-100 ft/s at an angle of 10° drops a package at t-0. Assume that the horizontal wind creates a constant resistance of 2 ft/s2 to the package in the x direction. The gravity is 32.2 ft/s (a) An automated laser gun in the same 2D plane is tracking the package. If at the instant the laser gun an= 9.292 ? records r-200'and ? 60°, determine t'è.H, and ? at ts]o sec. Hint: Decompose v, and v, into polar, and then a, and ay into polar. (b) Find a, an, and radius of curvature ? at t=10 sec. Use either dot product or decomposition Wind lo 9-32-2 1 ? los -200
