Think you are smart? Well try these brain teasers and face reality that you aren’t.
1) You’re on a train traveling up a 3 degree incline at 40 miles an hour. The train is decelerating at 2 m/s2, and you the friction coefficient between the trains wheels and the track is .2. How many more miles must you travel before you are safe from capture for the body the police will find in your basement one hour from now?
