While driving in the mountains, you notice that when the freewaygoes steeply downhill, there are emergency exits every few miles.These emergency exits are straight dirt ramps which leave the freeway and are sloped uphill. They are designed to stop trucks andcars that lose their brakes on the downhill stretches of the freeway even if the road is covered in ice. You are curious, so youstop at the next emergency road. You estimate that the road risesat an angle of 14 deg from the horizontal and is about 70 yards(210 ft) long. What is the maximum speed of a truck that you aresure will be stopped by this road, even if the frictional force of the road surface is negligible?
