A 12.5-kg crate slides along a horizontal frictionless surface at a constant speed of 3 m/s. The crate then slides down a frictionless incline and across a second horizontal surface as shown in the figure. What minimum coefficient of kinetic friction is required to bring the crate to a stop over a distance of 7 m along the lower horizontal surface? Hint: this problem is actually easier than it seems, and you only need to consider the two positions of the box shown below. Where did its energy go between the top of the ramp and the end? Also, the normal force acting on the box on the horizontal portions of the path is N- mg. V = 3 m/s v = 0 m/s 4 m 7 m
