# Velocity as a function of time?

#### bullroar_86

if an object has an acceleration of 22.3 m/s^2 [63.9 degrees E of S]

what is its "velocity as a function of time"

not sure what that means.. any ideas?

It means you have to find a function v(t) that relates the speed of the object, and the time elapsed.

Hint: The answer is in the definition of (constant) acceleration.

#### ayalam

v=vnot+at
vnot equals acceleration from the beginning of the problem.
v= velocity at a given time.

No, in that equation, "vnot" has to be the velocity at t= 0. And be sure to note that the velocity is a vector, not just a number.
