Answer: A truck with mass m has a brake failure while
Chapter 7, Problem 66P(choose chapter or problem)
A truck with mass m has a brake failure while going down an icy mountain road of constant downward slope angle \(\alpha\) (Fig. P7.66). Initially the truck is moving downhill at speed \(v_{0}\). 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 \(\beta\). The truck ramp has a soft sand surface for which the coefficient of rolling friction is \(\mu_{r}\). What is the distance that the truck moves up the ramp before coming to a halt? Solve using energy methods.
