P. 3978. A rod of mass m and length =1 m slides down on a slope such that one of its end slides along the slope and the other slides along the horizontal without friction. Initially the rod touches the incline, the figure shows a snapshot of the motion later.
a) Find the speed of the endpoints A and B when the rod reaches the horizontal position.
b) What are these speeds when the rod encloses an angle of 30o with the horizontal.
