When a body of mass M1 is hanging freely and another of mass M2 lying on a smooth inclined plane(α) are connected by a light index tensile string passing over a smooth pulley, the acceleration of the body of mass M1, will be given by

g(M1 + M2 sin α)/(M1 + M2) m/sec

g(M2 + M1 sin α)/(M1 + M2) m/sec²

g(M2 × M1 sin α)/(M2 - M1) m/sec²

g(M1 - M2 sin α)/(M1 + M2) m/sec²

g(M1 + M2 sin α)/(M1 + M2) m/sec

g(M2 + M1 sin α)/(M1 + M2) m/sec²

g(M2 × M1 sin α)/(M2 - M1) m/sec²

g(M1 - M2 sin α)/(M1 + M2) m/sec²

The following statement is one of the laws of Dynamic friction

The force of friction always acts in a direction opposite to that in which a body is moving

The magnitude of the kinetic friction bears a constant ratio to the normal reaction between two surfaces. The ratio being slightly less than that in the case of limiting friction

For moderate speeds the force of friction remains constant but decreases slightly with the increase of speed

All of these
