A 24 kg mass sitting on a horizontal bench, just starts to slide when a 14.0 kg mass hangs from a pulley (connected at 90°). Find (a)Draw a labelled diagram, with a sign convention and list all knowns etc (b) the co-efficient of static friction for the horizontal surface (c) the acceleration of the 24 kg mass sideways if the co-efficient of kinetic friction is 0.1
