. Problems in physics. Derived from military situations and experience . the wind is blowing? When theplane is headed 20 degrees away from the direction towardwhich the wind is blowing? 60. The air-speed meter indicates 70 miles per hour, the compass shows that the plane is headed 90 degrees from North,through East, the drift-bar of the bomb-sight makes anangle of 20 degrees with the fuselage. What is the ground-speed and its direction? 61. A pilot is flying a straight course directly away from the wind. Which way must he turn in order to make use of the drift-bar of the bomb-sight shown in Figure 7? 62. A pilot flies with the wind in such a direction that objects seem to move along the drift-bar, set at zero, from end to compass reads due North. The pilot heads the planedue East and adjusts the drift-bar until objects on theground appear to move along it. If the drift-bar is foundto be set at an angle of 30 degrees with its zero position andthe air-speed has been constant at 70 miles per hour, what isthe wind-speed and the direction of the wind?^.
