Two planes, A and B, are flying at the same altitude. Their velocities are v₁ = 500 km/h and VB = 670 km/h such that the angle between their straightline courses is = 60°. (Figure 1) B VA - 500 km/h Determine the magnitude of the velocity of plane B with respect to plane A. Express your answer in kilometers per hour to three significant figures. Determine the direction angle of the velocity of plane B with respect to plane A, measured counterclockwise from the positive x axis. Express your answer in degrees to three significant figures.

Two objects flies towards each other. When the distance between them is 1.3 km their velocities and acceleration are as follows:        vA = 44 m/s , vB  = 24 m/s , aA  = -0.1 m/s2  and  aB = 1.1 m/s2 A third object (C) left object A and moves towards object B with velocity of 43 m/s. Upon reaching B, it then flies back to A and so on until A and B meets. Determine the following:      a. Time it takes for ball A and B to meet      b. Where ball A and B will meet with respect to the initial position of A?      c. What is the total distance travelled by the third object?

The jet transport B is flying north with a velocity vB = 595 km/h when a smaller aircraft A passes underneath the transport headed in the 57° direction shown. To passengers in B, however, A appears to be flying sideways and moving east. Determine the magnitudes of the actual velocity of A and the velocity which A appears to have relative to B.
