Can anyone help with this physics question?!?
Water skiers often ride to one side of the center line of a boat. In this case, the ski boat is traveling at 15 m/s and the tension in the rope is 85 N. If the boat does 3500 J of work on the skier in 42.8 m, what is the angle θ between the tow rope and the center line of the boat?
°
The skier is on the lower left side of the boat. I tried dividing 3500J by 42.8 to get the force applied over that distance, but now i’m not sure what to do since i need to find the angle.
Let the angle between the angle between the tow rope and the center line of the boat = θ.
By W = F x s
=>W = T x cosθ x s
=>3500 = 85 x cosθ x 42.8
=>cosθ = 0.92 = cos23*
=>θ = 23*
