**Unformatted text preview: **2 7.66: Denote the distance the truck moves up the ramp by x. K1 = 1 mv0 , 2 U 1 = mgL sin , K 2 = 0 , U 2 = mgx sin and Wother = - r mgx cos . From Wother = ( K 2 + U 2 ) - ( K1 + U 1 ) , and solving for x, 2 (v0 2 g ) + L sin K1 + mgL sin x= = . mg (sin + r cos ) sin + r cos ...
