Knowing that v = - 8 m/s when t = 0 and v = 8 m/s when t = 2 s, determine the constant k. (Round the final answer to the nearest whole number. You must provide an answer before moving on to the next part.) k = m/s4

    a) We know that acceleration a=dv/dt

    So dv/dt=kt^2

    dv=kt^2dt

    Integrating we get

    v (t) = kt^3/3+C

    Puttin t=0

    -8=C

    Putting t=2

    8=8k/3-8

    k=48/8

    k=6
