3.3.2 Newton's second law

Question 2

Two blocks $P\,$ of mass 4 kg and $Q\,$ of mass 6 kg are connected by a light inextensible string. The string passes over a smooth pulley fixed at the top of a rough inclined plane. The plane is inclined at an angle of $25^\circ\,$ to the horizontal. Block $P\,$ lies on the plane and $Q\,$ hangs freely from the pulley with the string taut. Block $P\,$ is released from rest and accelerates up the plane at 1.5 ms^-2.

a.

Find the tension in the string

[3]

b.

Find the coefficient of friction between $P\,$ and the plane

[3]

c.

Find the force exerted on the pulley by the string
