A large heavy box is sliding without friction down a smooth plane of inclination θ. From a point P on the bottom of the box a small trolley A is moving along a straight line parallel to the y-axis( see figure) with a constant velocity of (sqrt(3)-1) m//s . At a particular instant assumed to be the x-y plane On a frictionless horizontal surface the angular speed of A with respect to B is: Two particles A and B are moving as shown in the figure. At this moment of time when the line OA makes an angle of 45(@) with the x - axis
