see, what you do is, u take the sin(30), times that by 50, since that will you get you your force in the x direction, then, times that by your distance you traveled which is eight meters, since f*d= work, or Joules, bam..there you go!

Oooh. Okay. Thank you!
But my teacher also mentioned converting the answer between cartesian and geometric vectors. And I have no idea how to do that D:
