The correct option is (D). It is clear from the force diagram of the helicopter that the net force on it is towards right, as the forces in vertically upward and downward directions cancel each other (since represented by arrows of equal length and in opposite directions). The arrow to the right is longer than the arrow to the left which means net force (right arrow minus left arrow) is acting towards right. Now by Newton's second law, Force = mass*acceleration, Or, F = ma
This implies net acceleration, a, will also be towards right or the helicopter is accelerating to the right.

it out. 2nd I have to use that drawing and draw it in a free body
diagram form in the x-axis and y-axis where the object is at the
origin and that the forces are arrows and then rotate it the degree...

For the remaining income, I get a total of $102,360. I missed
the ratio and thought it was divided equally, so should it be:
Conyers $34,120 ($102,360 x 1/3)
Bernard $68,240 (102,360 x 2/3)
Are the calculations above correct?
