Question
A, B & C three objects each with constant velocity. A’s speed is 10 m/s in a direction 
. The vorticity of B relative to A is 6 m/s at an angle of, cos-1(15/24) to PQ. The velocity of C relative to B is 12 m/s in a direction 
. Then the magnitude of the velocity of C is :-
. The vorticity of B relative to A is 6 m/s at an angle of, cos-1(15/24) to PQ. The velocity of C relative to B is 12 m/s in a direction . Then the magnitude of the velocity of C is :-Options
A.5 m/s
B.2
m/s
m/sC.3 m/s
D.4 m/s
Solution
