Question 14

Two masses M1 M_1\,M1​ of 2 kg and M2 M_2\,M2​ of 4 kg are connected by a light inextensible string. The string passes over a smooth pulley at the top of a rough plane inclined at 45∘ 45^\circ\,45∘ to the horizontal. M1 M_1\,M1​ rests on the plane and M2 M_2\,M2​ hangs freely. The system is released from rest and M1 M_1\,M1​ accelerates up the plane at 2.5 ms-2.

a.

Find the tension in the string

[3]
b.

Find the coefficient of friction between M1 M_1\,M1​ and the plane

[3]
c.

Find the force exerted on the pulley by the string
