A squirrel hops in a sled at 3.5 m/s and goes down a snow bank. The squirrel slides down the hill at a total linear distance of 6.5m. There is 1.3 N of kinetic friction force between the sled and the snow that acts on the sled. The total mass of the squirrel and the sled together is 0.85kg, the height of the snow bank is 3.5 m above the ground.

Use the work energy theorem to find the final velocity of the squirrel/sled combination when they reach the bottom of the hill. The magnitude of the gravitational acceleration is 9.8 m/s^2.?
