A boat moves through the water with two
forces acting on it. One is a 2.32×10^3 N
forward push by the motor, and the other is a1.79×10^3 N resistive force due to the water.What is the acceleration of the 1279.5 kg boat?

  • physics -

    2.32 - 1.79 = .53
    so
    F = ma
    .53 * 10^3 = 1279.5 a
    a = .414 m/s^2

    By the way this is not really true because water is accelerated along with the boat hull, making its mass appear larger. In hydrodynamics this is often called "added mass"

    thank you soo much damon
