The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.

Problem

Relative to the earth, the sailboat sails north with speed v0 = 6 knots (nautical miles per hour) and then sails east at the same speed. The telltale indicates the direction of the wind relative to the boat. Determine the direction and magnitude of the wind’s velocity (in knots) relative to the earth.
