Question

The position of an object at time t is given by s(t) = -4 - 2t. Find the instantaneous velocity at t = 6 by finding the derivative.

Answer 1

So we want to find the derivative of

\[\large s(t) = -4 - 2t\]

Well we know that the derivative of a constant, is 0. and the derivative of a term with a variable, is just the term. So

\[\large s'(t) = -2\]

This means at ANY time, the instantaneous velocity will be -2

Answer 2

Ahh okay thank you (:

Answer 3

No problem :)
