If the coefficient of static friction is less than that found above, and if the coefficient of kinetic friction between the block and the table is .05, find the time it takes for the 6kg mass to fall
If the coefficient of static friction is less than that found above, and if the coefficient of kinetic friction between the block and the table is .05, find the time it takes for the 6kg mass to fall 7m to the floor if the system starts from rest.
