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).

Draw a diagram!
The x-coordinate will be 10.0*cos60.0°
The y-coordinate will be 10.0*sin60.0°

What you have is a vector of length 10.0 m drawn from the origin at an angle of 60 degrees.
The x-coordinate of the head of the vector is at (10.0 m)(cos 60 degrees) and the y-coordinate is at (10.0 m)(sin 60 degrees).

what you do is take the sine and cosine of the angle and multiply the length times them let me show you.
Take sin60*10=y that equals your y coordinate because
sin=y/hypotenuse
then do the same with cos and that euqals your ex coordinate:
cos60*10=x
because cosine equals cos=x/hypotenuse
hope that helps
