Speedboat Pulling Skiers

  1. Apr 6, 2008 #1
    1. The problem statement, all variables and given/known data
    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. Relevant equations

    3. The attempt at a solution
    500cos30=433N * 2 for both skiers
    let Fb be the force of boat on water

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