2. The longest snake ever found was a python that was 10.0 m long. Suppose a coordinate system large enough to measure the python’s length is drawn on the ground. The snake’s tail is then place at the origin and the snake’s body is stretched so that it makes an angle of 60.0°, with the positive x-axis. Find the x and y coordinates of the snake’s head. (Hint: the y-coordinate is positive).
