s =(3t^2 - 2)^m v = ds/dt = m(3t^2 -2)^m^-^1(16t) v = m(3(2)^2 -2)^m^-^1(12) =12m(10)^m^-^1ms^-^2since velocity is the first derivitive of displacecemt with respect to time we differentiate the function of displacecemt to get the expression for velocity and plug in the given time in the expression to get the answer.
