I am given the information: A water-skier is pulled behind a motorboat with a rope 8m long. As she is approaching a ramp, she pulls herself 2m to the side of the path of the boat. It creates an angle of 14.5 degrees.
I am asked:
1.) how much of the tow rope force is in the forward direction?
2.) how much of the tow rope force is sidewards?
How do i find that info when i am not given any additional infor?

You can resolve that into vertical and horizontal components
The one perpendicular to motion wouild be Tension in the rope * sin 14.5
the one parallel ( question 1) Would be T cos 14.5
I am not sure about that T actually is . The length of the rope doesnt help.
I hope that give you a start
