In the image below, a box of mass M (2.3kg) was gently placed on a frictionless slope of θ = 28°. The spring had an initial rest length of 60.0 cm but was compressed 15 cm by the box.
(a) [3] Draw a complete, well-labeled free body diagram (FBD) for the box.
(b) [1] Draw x and y axes that are parallel and perpendicular to the slope. Label them.
(c) [2] If any forces in your FBD are not parallel to one of the axes, replace it by its x and y
components.
(d) [2] What is the magnitude of the force in the FBD that acts into the slope?
(e) [2] What is the magnitude of the force in the FBD that acts down and along the slope?
(f) [1] If the block is at rest, what is the net force on it in the direction that is parallel to the slope? What is the spring constant of the spring?
