The position of an object at time t is given by s(t) = 3 - 4t. Find the instantaneous velocity at t = 8 by finding the derivative.

OpenStudy (anonymous):

the derivative is -4...there is no constant..therefore the velocity is negative and means that is stopping

v(t) = derivative of s(t) = 0 - 4 = -4
