An object which is released from rest from the top A of a tower of height h will appear not to fall straight down due to the effect of the earth's rotation. It may be shown that the object has an eastward horizontal acceleration relative to the horizontal surface of the earth equal to 2v,w cos y, where v, is the free-fall

Question
2/99 An object which is released from rest from the top A of a tower of height h will appear not to fall straight down due to the effect of the earth's rotation. It may be shown that the object has an eastward horizontal acceleration relative to the horizontal surface of the earth equal to 2v,w cos y, where v, is the free-fall downward velocity, w is the angular velocity of the earth, and y is the latitude, north or south. Deter- mine the deflection b if h = 1000 ft and y = 30° north. From Table D/3, w = 0.7292(10 4) rad/sec and from Fig. 1/1, g = 32.13 ft/sec?. Ans. b 3.99 in. A h East
