Question

An automobile starts from rest and travels down a straight section of road. The distance s (in feet) of the car from the starting position after t seconds is given by s(t)=8t3

(a) Find the instantaneous velocity (in feet per second) at t=5 seconds.

Instantaneous velocity at t=5 is ft/s.

(b) Find the instantaneous velocity in (feet per second) at t=8 seconds.

Instantaneous velocity at t=8 is ft/s.
