A car with a velocity of 25m/s [E] changes its velocity to 25m/s in 15s .(adsbygoogle = window.adsbygoogle || []).push({});

Calculate the car's average acceleration.

I have found out that the direction of the acceleration is 45degrees s of w.

But I have no idea about the magnitude of it...

and another similar problem is that:

a watercraft with an initial velocity of 0.4m/s [E] undergoes an averager acceleration of 2 m/s/s for 2.5s. waht is the final velocity of ther watercraft?

Thank you very much...
