Question

Problem 6: A block of mass m rests against a spring with a spring constant of k on an inclined plane which makes an angle of 0 degrees with the horizontal. Assume the spring has been compressed a distance d from its neutral position. Refer to the figure. Idl м tus Ctheexpertt eted eted eted eted eted Set your coordinates to have the x-axis along the surface of the plane, with up the plane as positive, and the y-axis normal to the plane, wim of the plane as positive. Denoting the coefficient of static friction by ,, write an expression for the sum of the forces in the x-direction just beforcs block begins to slide up the inclined plane. Use defined quantities andg in your expression.
