Question:

As shown in the figure, the jet transport B is flying north with a velocity v_B = 600 km/h when a smaller aircraft A passes underneath the transport headed in the 60 degree direction shown. To passengers in B, however, A appears to be flying sideways and moving east. Determine the actual absolute velocity of A and the velocity of A appears to have relative to B.      

A jet aircraft pulls up into a vertical curve as shown in the figure. As it passes the position where Θ=30^o, its speed is 1000 km/h and is decreasing at the rate of 15 km/h per second. If the radius of curvature ρ of the flight path is 1.5 km at this point, calculate the corresponding horizontal and vertical components, Ÿ and ? , of the acceleration of the aircraft.
