Velocity of the ball

Question

A ball's position, in meters, as it travels every second is represented by the position function s(t) = 4.9t² + 550.

What is the velocity of the ball after 3 seconds?Include units.

Answer 1

Velocity is the first derivative of displacement.

So you are taking the first derivative of s(t) as s'(t), then plug in your seconds.

Also, unit should be meter per seconds.
