The position of an object at time t is given by s(t) = -9 - 5t. find the instantaneous velocity at t = 4 by finding the derivative.

Instantaneous Velocity is

Step-by-step explanation:

Velocity refers to the speed along with direction or we can say velocity refers to rate of change of position of an object with respect to time.

Let be the position of object . Then the instantaneous velocity is given by . At time , velocity is given by

Given:

On differentiating with respect to time t , we get :

At ,

this is false ^.^ lol
