S(t) Is the Position of a Body Moving Along a Coordinate

Short Answer

s(t) is the position of a body moving along a coordinate line; s(t) is measured in feet and t in seconds, where $t \geq 0$ . Find the position, velocity, and speed of the body at the indicated time. $s(t)=\frac{4 t}{t^{2}+1}$ ; t = 3
