An out of control truck with a mass of 7500 kilogram is traveling at 13 meter per second (about 30 miles per hour) when it locks up its brakes and starts descending an icy hill with a 5o incline. The coefficient of kinetic friction between the trucks tires and the icy road is .27. Use the work- energy theorem-
a. Find how far the truck will slide down the slope with its brakes locked up before it comes come to rest and stops?
b. Find how far will the truck slide if the truck has the same magnitude of speed but different direction up the hill when the brakes lock up?
