The Figure Shows a Block of Mass M Resting on a 20°

question 140

Multiple Choice

The figure shows a block of mass m resting on a 20° slope.The coefficients of friction between the block and the surface of the slope are $\mu _ { \mathrm { S } } = 0.64$ and $\mu _ { \mathrm { k } } = 0.54$ It is connected using a very light string over an ideal pulley to a hanging block of mass 2.0 kg.The string above the slope pulls parallel to the surface.What is the minimum mass m so the system will remain at rest when it is released from rest? $The figure shows a block of mass m resting on a 20° slope.The coefficients of friction between the block and the surface of the slope are \mu _ { \mathrm { S } } = 0.64 and \mu _ { \mathrm { k } } = 0.54 It is connected using a very light string over an ideal pulley to a hanging block of mass 2.0 kg.The string above the slope pulls parallel to the surface.What is the minimum mass m so the system will remain at rest when it is released from rest?
