일반물리학 1 — Force and Motion-I: Problem 64

64 Figure 5-46 shows a box of mass \(m_2 = 1.0 \text{ kg}\) on a frictionless plane inclined at angle \(\theta = 30^\circ\). It is connected by a cord of negligible mass to a box of mass \(m_1 = 2.5 \text{ kg}\) on a horizontal frictionless surface. The pulley is frictionless and massless. (a) If the magnitude of horizontal force \(\vec{F}\) is \(2.3 \text{ N}\), what is the tension in the connecting cord? (b) What is the largest value the magnitude of \(\vec{F}\) may have without the cord becoming slack?
