Particles P and Q have masses 0.3 kg and 0.6 kg respectively. The particles are held at rest at a distance of 2.75 m apart on a line of greatest slope of a rough plane inclined at angle $ \alpha $ to the horizontal, where $ \sin\alpha = 0.28 $ (see diagram). The coefficient of fr…

Two particles A and B of masses km and m respectively, where k and m are constants, are free to move in a straight line on a smooth horizontal plane. Particle A is projected towards B with speed 2u and at the same instant B is projected towards A with speed u. The particles colli…

Two particles, $A$ and $B$, of masses 3kg and 6kg respectively, lie on a smooth horizontal plane. Initially, $B$ is at rest and $A$ is moving towards $B$ with speed $8\mathrm{~m}\mathrm{s}^{-1}$. After $A$ and $B$ collide, $A$ moves with speed $2\mathrm{~m}\mathrm{s}^{-1}$. Find…
