I've been doing this question for a while but I can't seem to get the right answere. I end up with three unknowns and I can't see what I'm doing wrong.(adsbygoogle = window.adsbygoogle || []).push({});

Two particles A and B, of mass 8kg and 10kg respectively are connected by a light inextensible string which passes over a light smooth pulley P. Particle b rests on a smooth horizontal table and particle A rests on a smooth plane inclined at 30 degrees to the horizontal with the string taut and perpendicular to the line of intersection of the table and the plane as shown below.

The system is released from rest.

a) Find the magnitude of the acceleration of particle B

b) Find, in newtons, the tension in the string.

c) Find the distance covered by B in the first two seconds of motion, given B does not reach the pulley.
