Question

Problem 12.141 < 1 of 7 > Review A package is dropped from the plane which is flying with a constant horizontal velocity of VA = 200 ft/s. Suppose that h = 1950 ft. (Figure 1) Part A Determine the normal component of acceleration at the moment the package is released at A, where it has a horizontal velocity of A = 200 ft/s. Express your answer to three significant figures and include the appropriate units. (an)A = 32.25 Submit Previous Answers Correct Part B Figure < 1 of 1 > Determine the tangential component of acceleration at the moment the package is released at A.
