A marble block of mass 2 kg lying on ice when given a velocity of 6m//s is stopped by friction in 10s. Then the coefficient of friction is

Given in figure are two blocks A and B of weight 20N and 100N, respectively. These are being pressed against a wall by a force F as shown. If the coefficient of friction between the blocks is 0.1 and between block B and the wall is 0.15, the frictional force applied by the wall on block B is:
