In the arrangement shown in fig., at a particular instant, the roller is coming down with a speed of 12ms^(-1) and C is moving up with 4ms^(-1) . At the same instant, it is also known that w.r.t. pulley P, block A is moving down with speed 3ms^(-1) . Determine the motion of block B (velocity ) w.r.t. ground.

A thin uniform rod of mass 5 kg and length 1 m is held in horizontal position with the help of strings attachedd to ends of rod. Other ends of strings are held by some external agent. Now end A is pulled down with speed v_(A)=3t and end B is pulled down with speed v_(B)=t , where t is time in second. Choose the correct choice(s)
