can someone solve this in more details please??

can ny1 solve the last question 7(f)?

halosh92:
a particle A of mass "m" which can move on the rough surface of an inclined plane at an angle X to the horizontal.
where X=arcsin 0.6
a second particle B of mass "2m" hangs freely attached to a light inextensible string which passes over a smooth pulley fixed at P. the other end of the string is attached at A . the coefficient of friction between A and the plane is 1/4.
B is initially hanging 1m above the ground and A is 2m from the pulley. when the system is released from rest with the string taut A moves up the plane
a) find the initial acceleration of A
b) calculate the total distance moved by A before it first comes to rest.
