Situation 6.1 a 13.5-kg box slides over a rough patch 1.75 m long on a horizontal floor. just before entering the rough patch, the speed of the box was 2.25 m/s, and just after leaving it, the speed of the box was 1.20 m/s. in situation 6.1, the magnitude of the average force that friction on the rough patch exerts on the box is closest to: a) 19.5 n b) 14.0 n c) 13.7 n d) 5.55 n e) it is impossible to know since we are not given the coefficient of kinetic friction
