Unformatted text preview: joining (0 , 4 , 2) and (6 , , 2) is a diameter. 4. An airplane ﬂying at constant altitude has an airspeed of 600 mph. If the pilot is steering the plane in the direction N30 o E (30 o east of north) and the wind is blowing from the northwest (N45 o W) at 50 mph, ﬁnd the magnitude and direction of the resultant velocity vector. (The direction of the resultant velocity vector is called the true course of the plane and the magnitude is called the ground speed.) 5. (a) Find the angle between the diagonal of a cube and one of its edges. (b) Find the angle between the diagonal of a cube and the diagonal of one of its faces. 1...
