A 31 kg crate full of fruits is placed on an incline that is 17â—¦below the horizontal. The crate is connected to a spring that isanchored to a vertical wall, such that the spring is parallel tothe surface of the incline.
(a) If the crate was connected to the spring at equilibriumlength, and then allowed to stretch the spring until the cratecomes to rest, determine the spring constant. Assume that theincline is frictionless and that the change in length of the springis 2.13 m.
(b) If there is friction between the incline and the crate,would the spring stretch more, or less than if the incline isfrictionless? You must use concepts pertaining to work andenergy.
