The coefficient of friction is u. (For wooden blocks, u is typically in the range of 0.2 to 0.5.) Find the value of 6 at which the block starts to slide, and the acceleration X when it slides. In the absence of friction, the block would slide down the plane; hence the friction force f points up the plane.

Problem A block with a mass of 15 kg sits on the smooth incline shown below where the angle is e = 37°. The block is attached to the wall via a spring with a spring constant of k = 246 N/m. The coordinate system for this problem is oriented as shown in the diagram. Based on this information, answer the following: a) Determine the distance the spring must stretch to offset the weight component of the block in the x-direction (this is where your x-direction datum will be located). b) Create a free body diagram and use the force balance in the x-direction to develop the second-order ordinary differential equation governing the motion of the block (your force balance should be based upon the datum found in part a). c) Find the natural frequency (wn), the period of vibration (T), and the frequency (f). d) For an undamped, freely vibrating system the solution to the second-order ordinary differential equation developed in part b has the form x(t) = Asin(wnt) + Bcos(wnt).
