Can anyone help with a Calculus proof?

Using derivatives a = dv/dt, v = ds/dt and |v| = speed, show that if an object is moving on a straight line, then its speed is increasing when its velocity v and its acceleration a have the same sign and its speed is decreasing when v and a have opposite sign.
