Question

The position of a particle moving along a coordinate line is s=57+4t​, with s in meters and t in seconds. Find the rate of change of the​ particle's position at t=6 sec.

The rate of change of the​ particle's position at t=6 sec is ____m/sec.

Answer 1

4 meters per second = s'(t) = s'(6) = 4

the rate of change = velocity = a constant 4 regardless of the value of t
