(10\%) Problem 4: You give a crate of mass m=1.00kg an initial speed of vi?=4.00m/s up an incline of ?=44.7. The crate then slides along the incline, reaches a spring of spring constant k=75.9N/m, and compresses the spring by ?s=15.0cm before stopping. A 25% Part (a) Assuming there is no friction, what is the distance, d, in meters, along the incline that the crate slides? d=m25% Part (b) What distance, ds?, in meters, had the crate moved when it just touched the spring? ds?=mD A 25% Part (c) If there were friction between the crate and incline, which of the options below woald be the correct equation for the magnitude of the kinetic friction force? fk?=?k?mgfk?=?k?mgcos?fk?=?k?cos?fk?=?k?mgman?fk?=?k?mgsin?fk?=mgcos?? i 25% Part (d) If there were friction between the crate and incline, what value of the coefficient of kinetic friction would stop the crate after it travels a distance, d1?, stopping just before it begins to compress the spring? ?k?= Grade Summary Dedections Poeential 1005
