Bill and Jill both average swimming speeds of 3.0 m/s, in a pool (that has no current). Bill and Jill go down to the river for a swim, the river has a current of 1.0 m/s straight EAST and is 1.50 x 102 m in width. They are standing on the SOUTH shore. a.Bill, not thinking about the current, jumps in and swims straight across to the North shore. Of course the current affects his resultant velocity and he doesn’t end up directly North of his starting position. Fi nd his resultant velocity.b.Jill, thinking about the current, jumps in and points herself in a direction that WILL allow her to end up directly North of her starting position. Find the direction that Jill pointed herself (i.e. where she would go if there was no current)c.Find Jill’s resultant velocity in part b.d.Find how long (how much time) it took BOTH Bill and Jill to cross the river.e.How far apart were Bill and Jill when they reached the North bank?
