The figure shows a block of mass m resting on a 20° slope.The block has coefficients of friction µs = 0.55 and µk = 0.45 with the surface.It is connected via a massless string over a massless,frictionless pulley to a hanging block of mass 2.0 kg.What is the minimum mass m that will stick and not slip?
A)2.3 kg
B)3.9 kg
C)1.4 kg
D)3.8 kg
