Suppose that an object is traveling along a straight line. Suppose that its velocity function is given by
v(t) = 8t^2 -5t
where t is in seconds.
Find the object's instantaneous acceleration at t=3 seconds.
An object is traveling in a straight line according to the position function
f(t) = 4t^2 -t
t is in seconds. Find the instantaneous velocity at t= 4 seconds
