2000 kg boat, motor force of 6000 N, resistance 2000 N

  1. Dec 17, 2015 #1
    1. The problem statement, all variables and given/known data
    A 2000 kg boat's motor can exert a force of 6000N. The water provides a resistive force of 2000N. What is the magnitude of the acceleration.

    2. Relevant equations


    3. The attempt at a solution
    that the boat has a 4000 N total force going foward

    Right. What standard equations might be relevant?

    acceleration= all forces working on object/mass?

    Sort of. To be accurate, Acceleration = net force on object / mass.

    so the acceleration would be 2 m/s?

    m/s is a speed, not an acceleration.

    oh 2m/s^2?
