Question

help asap physics homework, i’ll give brainliest
A boat moves through the water with two forces acting on it. One is a 2000-N forward push by the water on the propeller, and the other is an 1800-N resistive force due to the water around the bow.
(a) What is the acceleration of the 1000-kg boat?
(b) If it starts from rest, how far will it move in 10.0 s?
(c) What will its velocity be at the end of this time?

    Answer:

    a= 0.2 m/s^2\\s = 20m\\t = 2 s

    Explanation:

    gievn

    two forces are given

    f_{1} = 2000 N \\f_{2} = 1800 N\\F_{net} = 2000 -1800 = 200N

    A) (a) What is the acceleration of the 1000-kg boat?

    f_{net} = ma\\a = \frac{f_{net}}{m}

         a = \frac{200}{1000}\\a= 0.2 m/s^2

    B) If it starts from rest, how far will it move in 10.0 s?

    using kinematic equation

    s = ut +\frac{1}{2}at^2\\ u = 0 \ m/s\\\\S = \frac{1}{2} at^2 \\s = \frac{1}{2} \times 0.2 \times (10)^2\\s = 10 m

    (c) What will its velocity be at the end of this time?

    v= u +at \\u = 0 m/s \\v = 0.2\times 10\\v = 2 m/s
