Question
In the previous Problem Set question, we started looking at the position function s (t), the position of an object at time t. Two important physics concepts
are the velocity and the acceleration.
If the current position of the object at time t is s (t), then the position at time h later is s (t + h). The average velocity (speed) during that additional time
(s(t+h)-s(t))
h
his
If we want to analyze the instantaneous velocity at time t, this can be made into a mathematical model by taking the limit as h→0,
i.e. the derivative s' (t). Use this function in the model below for the velocity function v (t).
The acceleration is the rate of change of velocity, so using the same logic, the acceleration function a (t) can be modeled with the derivative of the velocity
function, or the second derivative of the position function a (t) = v' (t) = s″ (t).
