During this time interval, the unbalanced forces are the downward forces which include drag force and weight of the object.

Net force on the object

The net force on the object is obtained by summing all the forces acting on the object.

Let the upward force = positive

Let the downward force = negative

  • Thrust force (upward) = 50 N
  • Drag force (downward) = 20 N
  • Lift force (upward)  = 40 N
  • Weight (downward) = 40 N

Net force = (50 N + 40 N) - (20 N + 40 N)

Net force = 90 N - 60 N = 30 N

Thus, during this time interval, the unbalanced forces are the downward forces which include drag force and weight of the object.
