1. The problem statement, all variables and given/known data A watermelon seed has the following coordinates: x = -8.1 m, y = 8.8 m, and z = 0 m. Find its position vector 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 (3.3 m, 0 m, 0 m), what is its displacement as (c) a magnitude and (d) an angle relative to the positive direction of the x axis? 2. Relevant equations 3. The attempt at a solution a= 11.9 Meters b= 133 degrees c= 15.2 Meters d = ???? How do I find this final angle??
