a A 2.0 kg breadbox on a incline of angle 8 = 30° is connected, by a cord that runs over a pulley, to a light spring of spring constant k = 120 N/m, as shown in the Figure 4. The coefficient of kinetic friction between box and the inclined plane is Mik = 0.52, The box is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless and the system is isolated. (a)...
Chapter 08, Problem 030- second time asking this question....only need part A A 2.3 kg breadbox on a frictionless incline of angle θ = 38 ˚ is connected, by a cord that runs over a pulley, to a light spring of spring constant k = 120 N/m, as shown in the figure. The box is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless. (a) What is the speed of the box when...
