    1. The problem statement, all variables and given/known data

    A net force of 14 N accelerates a 9 kg mass over a distance of 8 m.

    What is the increase in kinetic energy of the mass?

    2. Relevant equations

    P = W x T

    3. The attempt at a solution

    8 x 14
    9 = 12.44 but its wrong
