A boat moves through the water with two forces acting on it. One is a 1500 N forward push by the motor, and the other is an 1400 N resistive force due to the water.
(a) What is the acceleration of the 1100 kg boat?
m/s 2
(b) If it starts from rest, how far will it move in 7.0 s?
(c) What will its velocity be at the end of this time?

  • Physics -

    (a) net force = M * a
    Solve for a. The net force is 100 N

    (b) X = (a/2)t^2
    Use the acceleration "a" from part a.
    t = 7 s.
    (c) V = a * t
