Which is the sequence of correct blood flow

A boat is moving with a velocity (3hati-4hatj) with respect to ground. The water in river is flowing with a velocity (-3hati-4hatj) with respect to ground. What is the relative velocity of boat with respect to river?

A small body tied to one end of the string is whirled in a vertical circle. Find the velocity and tension at the lowest and highest point of the circle respectively.
