Hi there,

Come on. I believe you can answer that by yourself. You just need to apply the accelerated linear motion equations and you get to your answer

Not really, but I can help you find them.

Acceleration is define as a variation of speed: [tex]a = \frac{v_1 - v_0}{t}[/tex]

In the case of accelerated linear motion, the average speed is equal to the mean speed: [tex]\overline{v} = \frac{v_0 + v_1}{2}[/tex]

From these three equations, you have the solution to your question.

Hi shahzadzai!

They are the standard constant acceleration equations see the PF Library.
