1. Homework Statement
300 kg speedboat is pulling two 25 kg skiers using ropes. Each rope makes an angle of 30 with the boat axis. Each rope exerts 500N force and acc. is 2m/s^2. What force must the boat exert on water to keep skiers moving?

2. Homework Equations
a=Fnet/m


3. The Attempt at a Solution
500cos30=433N * 2 for both skiers
let Fb be the force of boat on water
2=(Fb-866N)/300
Fb=600+866
Fb=1466N

Didnt use mass of skiers, so any help is appreciated. Dont know if it is right.
