6.Two particles P and of masses 3 kg and 7 kg are connected bya light inextensible string.Particle P lies on a rough horizontaltable,and there is a smooth pulley fixed to the edge of the table.The string passes over the pulley and particle hangs freely 0.5 mabove horizontal ground,with the string taut.Particle Pexperiences a frictional force of 2 The system is released fromrest.a)Find the acceleration of the particles.[4]b)Find the tension in the string.[2]Given that the particle P never reaches the pulley:c)Find the time taken for particle to reach the ground [3]d)Find the speed of particle P when particle hits the ground[2]e)Find the total distance travelled by particle P before it comesto rest [6]f)Explain how you have used the fact that the pulley is smoothin your calculations.[1]
