5.7 Exercise 38

Suppose that you are viewing a soccer game from a helicopter above the playing field. Two soccer players simultaneously kick a stationary soccer ball on the flat field; the soccer ball has mass 0.420 kg. The first player kicks with force 162 N at $9.0 °$ north of west. At the same instant, the second player kicks with force 215 N at $15 °$ east of south. Find the acceleration of the ball in $\hat{i}$ and $\hat{j}$ form.
