Figure shows a block placed on a bracket. Bracket is placed on a smooth floor, it is pulled by a force F=6N horizontally Block is projected with velocity v_(0) relative to bracket as shown in figure. Find time in second after which it stops relative to bracket. Horizontal surface of bracket is smooth while vertical surface is rough (Given `m=1 kg M=5 kg v_(0)=5 m //s mu =0.5)` (Round off nearest integer)
