Question

please dont waste my time with those 'answer is in the file"
The force exerted by water and air on the skier is 50 Newtons (N) to the left. The force exerted by the boat on the skier is 40 Newtons (N) to the right. How will the unbalanced forces change the motion of the skier

Actually Welcome to the concept of Net force on a body.

We know that net force on a body is the force that is calculated from all direction and added , if there is any force remained at last, then the forces are unbalanced,

and if the net force on a body is Zero, then it is a balanced force,

here,

Force to left on skier = 50 N

Force to right on skier = 40 N

hence the net force = left force - right force

Net force = 50 - 40 ==> 10 N

hence the Net force is 10 N in the left direction of the skier.
