A block is at rest on a rough inclined plane and is connected to an object with the same mass as shown. The rope may be considered massless; and the pulley may be considered frictionless. The coefficient of static friction between the block and the plane is mu s; and the coefficient of kinetic friction is mu k . What is the magnitude of the static frictional force acting on the block?Explanation / Answer
normal reaction on the block = mgcos(theta)
static friction force = us*mgcos(theta)
