Question

In order to determine the velocity, you must know

the distance and the time.
the direction and speed.
the time and speed.
the direction and time.

Answer 1

\[v(t)=s'(t) = \frac{ \Delta x }{ \Delta t }\]

\[\Delta x = ?\]

\[\Delta t =?\]

Answer 2

change in displacement per time is know as velocity
