The position of an object at time t is given by s(t) = -8 - 9t. find the instantaneous velocity at t = 1 by finding the derivative.

need asap, you!

At t = 1s, The instantaneous velocity will be -9

Step-by-step explanation:

The position is given by

s(t) = -8 - 9t

If we find the derivative, we get the expression for the velocity

d(s(t))/dt = v(t) = -9

The velocity of the object is constant.

At t = 1s, it will be -9
