A block m1= 0.5kg slides on a plane inclined at 300 to the horizontal. It is attached to a string which runs over a pulley and has a mass m2=0.2kg hanging at the other end. The coefficients of friction between the block m1 and the plane are: μs = 0.4 and μk = 0.3 . Assume that at t=0s, the block m1 is moving down the incline. Refer to this moment and: a) Draw FBD for both blocks. b) Write the second law for both of them c) Find the magnitude of acceleration of set of masses. d) Find if mass m1 is speeding up or slowing down.
