Two objects with masses M1 and M2 are suspended on a smooth pulley by an inelastic string as shown in
figure 1 below
Figure 1

(a)	Explain the terms.
(i) (ii)	Smooth pulley Inelastic string	(2 marks) (3 marks)	(b)
Copy the diagram and indicate all the forces acting in the system.
(c)	If M1<M2, indicate the direction of the motion of each particle on the diagram in (b) above and
establish the equations of motion for the system.	(5 marks)
(d)	Given that M1 = 2kg and M2 = 3kg, calculate the tension in the string and the acceleration of the
system.	(4 marks)
(e)	State one condition necessary for the system to be in equilibrium.	(1 mark)
