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.
Answer:
\(s'(8)=-4\)
Step-by-step explanation:
The position of an object at time t is given by \(s(t) = 3 - 4t\)
To find instantaneous velocity we take derivative
LEts take derivative of s(t)
\(s'(t)= -4\)
we need to find the instantaneous velocity at t = 8
So we plug in 8 for 't' in the derivative. there is no 't' in the derivative
So, \(s'(8)=-4\)
