Transcribed Image Text:7.58 A truck with mass m has a brake failure while going down
an icy mountain road of constant downward slope angle a (Fig. P7.58).
Initially the truck is moving downhill at speed up. After careening
downhill a distance L with negligible friction, the truck driver steers the
runaway vehicle onto a runaway truck ramp of constant upward slope
angle ẞ. The truck ramp has a soft sand surface for which the coefficient
of rolling friction is μr. What is the distance that the truck moves up the
ramp before coming to a halt? Solve by energy methods.
