an ideal physics text with a mass of 2.5g is placed on a rough incline. The coefficients of static and kinetic friction are .3 and .2 respectively. A massless string is connected over a frictionless pully and a mass m is attached. what is the maximum mass that can be suspended without the text slidingz? If the mass is actually 10 kg, what is the magnitide of the acceleration of the text?
