A small boat is moving at a velocity of 3.35m/s when it is accelerated by a river current perpendicular to the initial direction of motion. The current accelerates the boat at 0.750m/s^2. what will the new velocity (magnitude and direction) of the boat be after 5 s?

    v = 7.1 m/s

    Explanation:

    Given that

    u = 3.35 m/s

    t = 5 s

    a = 0.75 m/s²

    The final velocity = v

    We know v = u + at

    v=final velocity

    u=initial velocity

    Now by putting the values in the above equation

    v = 3.35 + 0.75 x 5 m/s

    v = 7.1 m/s

    Therefore the final velocity will be 7.1 m/s
