A watermelon seed has the following coordinates: x =-6.4 m, y = 5.0 m, and z = 0 m. Find its positionvector as (a) a magnitude and (b)an angle relative to the positive direction of the x axis.If the seed is moved to the xyz coordinates (3.0 m, 0 m, 0m), what is its displacement as (c) a magnitudeand (d) an angle relative to the positivedirection of the x axis? Put the angles in the range(-180°, 180°].
