1 a) A particle P of mass m is placed on a rough plane inclined at an angle tan-1 (5/12) to the horizontal.The coefficient of friction between the plane and P is 0.5. Prove that P will remain stationary. 1b ) A light inextensible string is fastened to P, passes up a line of greatest slope, over a frictionless pulley at the top of the plane, and to its other end is attached a particle Q of mass 2m , which hangs freely. Prove that the particles will move and find magnitude of their acceleration. 1c ) When Q has decended a distance h , it hits the floor and rebounds with 0.5 of its speed. Show that Q will hit the floor again before P comes to instantaneous rest. I cant solve the problem of 1C ) Someone pleae help. No diagram is included in the question orginally. Answers for 6b) a= 5g/13 = 3.846 ms-2 6c) T(Q) = 1.387(h)^0.5 Means Root h T(P)=0.3396(h)^0.5 = 1.074(h/g)^0.5 So t(Q) < t(P) PLEASE HELP!
