a) If you are at the top of a toboggan run that is 40.0 m high, how fast will you be going at the bottom, provided you can ignore friction between the sled and the track?
b)Does the steepness of the run affect how fast you will be going at the bottom?
c)If you do not ignore the small friction force, does the steepness of the track affect the value of the speed at the bottom?
