Truck brakes can fail if they get too hot. In some mountainous areas, ramps of loose gravel are constructed to stop runaway trucks that have lost their brakes. The combination of a slight upward slope and a large coefficient of rolling friction as the truck tires sink into the gravel brings the truck safely to a halt. Suppose a gravel ramp slopes upward at 6.0° and the coefficient of rolling friction is 0.32. Part A Use work and energy to find the length of a ramp that will stop a 15,000 kg truck that enters the ramp at 35 m/s. Express your answer to two significant figures and include the appropriate units.

Truck brakes can fail if they get too hot. In some
mountainous areas, ramps of loose gravel are
constructed to stop runaway trucks that have lost
their brakes. The combination of a slight upward
slope and a large coefficient of rolling friction as the
truck tires sink into the gravel brings the truck
safely to a halt. Suppose a gravel ramp slopes
upward at 6.0° and the coefficient of rolling friction
is 0.32.
Part A
Use work and energy to find the length of a
ramp that will stop a 15,000 kg truck that
enters the ramp at 35 m/s.
Express your answer to two significant
figures and include the appropriate units.
