I would understand how to do this question if perhaps we were given values for the radius and velocities but we are not.

1. You are at a point A on the shore of a circular lalre with radius R. You want to get to the point B which is diametrically opposite from A. There is a boat at A. You could row in a straight line from A to B. You could also run around the lake all the way from A to B. Dr you could row the boat from A to some point C on the coast somewhere in between A and E, abandon the boat, and then run to B. Assume that you can run with velocity 1:1 and that you can row with velocity 1P3. Assume tl'g ac: in (otherwise? the problem is very easy, can you see why?) 1Where should the point C be located in order to get from A to B as fast as possible? Your answer will? of course? depend on the values of 1:1 and g. G
