Homework Help: Physics

Posted by Andrea on Sunday, September 5, 2010 at 5:21pm.

If someone could point me in the right direction-please!!!
A car with an initial speed of 4.30m/s accerlerates uniformly at the rate of 3.00 m/s ^2. Find final speed after 5.00s.

Thanks for any help you can provide.

Acc. = (Vt - Vo) / t
3m/s^2 = (Vt - 4.3m/s) / 5.0s,
3 = (Vt - 4.3) / 5,
Cross multiply:
Vt - 4.3 = 15,
Vt = 19.3m/s
