You are riding a sled across frictionless ice. It has been given an initial push and is now traveling at a constant velocity, in a straight line.Snow is falling vertically (as seen by a person standing still on the ice), and the snow is accumulating on the sled. You have three strategies fortrying to keep the sled moving as fast as possible:
a)Sweep the snow off the sled so that it leaves the sled in the direction perpendicular to the sled's motion, as seen by you in the reference frame of the sled.
b) Sweep the snow off the sled so that it leaves the sled in the direction perpendicular to the sled's
motion,as seen by you in the reference frame of someone standing still on the ice.
c) Do nothing.
