Question

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 1

I hope this helps you

s' (t)=0-4


s' (t)=-4

t=8


s' (8)=-4

Answer 2

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, $s'(8)=-4$
