Answer: A block with mass m1 is placed on an inclined
Chapter 5, Problem 5.77(choose chapter or problem)
A block with mass \(m_1\) is placed on an inclined plane with slope angle a and is connected to a hanging block with mass \(m_2\) by a cord passing over a small, frictionless pulley (Fig. P5.74). The coefficient of static friction is \(\mu_\mathrm s\), and the coefficient of kinetic friction is \(\mu_\mathrm k\). (a) Find the value of \(m_2\) for which the block of mass \(m_1\) moves up the plane at constant speed once it is set in motion. (b) Find the value of \(m_2\) for which the block of mass \(m_1\) moves down the plane at constant speed once it is set in motion. (c) For what range of values of \(m_2\) will the blocks remain at rest if they are released from rest?
