A person in a kayak starts paddling, and it accelerates from 0 to 0.498 m/s in a distance of 0.554m. If the combined mass of the person and the kayak is 62.6, what is the magnitude of the net force acting on the kayak?

  1. Use the formula

    F = m a

    to get the force in Newtons.

    In this case, m is the combined mass of kayak and the person paddling.

    You neglected to provide units for the combined mass. I assume it is kilograms.

    For the acceleration, a, assume uniform acceleration, in which case

    Vfinal = sqrt(2aX)

    a = Vfinal^2/(2X)

    X = 0.554 m
