You are speeding your 1800 kg truck down Ferguson on a Friday night at 29 m/s. You see a squirrel in the road
and slam on the brakes to avoid hitting it. The brakes plus the road friction generate 5000 N of force on the car,
How far will your car skid before it stops? Do you hit the squirrel if you were 100 m away when you started
braking?

= KE
W = Fd
KE =
