Given total time of given acceleration to get final velocity?

[pebbles]

can i just multiply the acceleration by time to get the final velocity? and then, if i wanted to get distance with the same three variables-time, acceleration, and velocity, would i just multiply velocity by total time i am given?



thanks in advance. I'm trying to clear some things up before my exam on thursday.

can i just multiply the acceleration by time to get the final velocity?

If the acceleration is constant:
$$v = v_0 + a t$$

and then, if i wanted to get distance with the same three variables-time, acceleration, and velocity, would i just multiply velocity by total time i am given?

The change in displacement will equal average velocity times the time.

Review the kinematic equations here: Basic Equations of 1-D Kinematics

what if acceleration isn't constant?

You would need to integrate acceleration with respect to time.

v = integrate[a dt]
