Question
Part A
A truck with mass m has a brake failure while going down an icy
mountain road of constant downward slope angle a (Figure 1).
Initially the truck is moving downhill at speed vo. 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 B. The truck ramp has a soft sand surface for
which the coefficient of rolling friction is lr .
What is the distance that the truck moves up the ramp before coming to a halt? Solve using energy methods.
Express your answer in terms of m, a, vo, L, g, ß and ur.
?
(vo +2gL sin a)
