Best ResponseYou've already chosen the best response.1Ah, this is a very important topic. "s" here is a position function. "b" is just a constant. We could assume it's any number, but we'll hold off on putting a number in there, since we don't know what it is. "t" is usually representing time in these problems. The rate of change of position, s, is called velocity. The derivative of the position function, s, with respect to t, is called ds/dt. To find the velocity of this position function, differentiate \[s = bt  16t^2.\] Note that they did not use the letter "a" for the constant. The derivative of the velocity is acceleration, usually labeled as "a". To summerize: velocity =\[\frac{ ds }{ dt }\] and acceleration =\[\frac{ d ^{2}s }{ dt ^{2} }.\]
