Answer:
And that represent the instantaneous velocity at a given time t.
And then we just need to replace t =2 in order to find the instantaneous velocity and we got:
Step-by-step explanation:
For this case we have the position function s(t) given by:
And we can calculate the instanteneous velocity with the first derivate respect to the time, like this:
And if we take the derivate we got:
And that represent the instantaneous velocity at a given time t.
And then we just need to replace t =2 in order to find the instantaneous velocity and we got:
