7) A particle is moving in space. The distance it has traveled from time t-0 to time t 8 is defined by the function s(t) = t3-10t2 + 21t a) Find the velocity function, v(t) by taking the derivative of s() b) Find the acceleration function, a(t) by taking the derivative of v(t). c) Plot s(t) as a red dashed line, v(t) as a blue solid line, and a(t) as a green dotted line, in three separate figure windows
