# Mechanics question watch

Announcements
1. A particle P of mass 5kg lies on an inclined plane where sin x=3/5. Particle Q is connected to a particle Q of mass 4kg by a light inextensible string which lies along a line of greatest slope of place and passes over a smooth peg. The system is held at rest with Q hanging vertically 2m above a horizontal plane. The system is released from rest.

B: Assuming p does not reach the peg find to 3 significant figures
(i) initial acceleration of q
(ii) how long it takes for q to hit the horizontal plane
(iii) total distance that p moves up the plane

Why not try posting in a specific subject forum- you might have more luck there.

Here's a link to our subject forum which should help get you more responses.

Have you tried anything yet?

Have you drawn a diagram that shows all of the forces acting in the system?
