The figure below shows two blocks connected by a string of negligible mass passing over a frictionless pulley. $m_1 = 7.6$ kg and $\theta = 12.0^\circ$. Assume that the incline is smooth. (a) For what value of $m_2$ (in kg) will the system be in equilibrium? $m_2 = \boxed{37}$ kg (b) If the block has to slide down the incline with an acceleration of 0.3 m/s$^2$, what should be the value of $m_2$ (in kg)? $m_2 = \boxed{}$ kg
