Is my longboard skateboard good for bombing hills or just cruising?

I'm almost 16, 4'9, and 97 pounds, I bought a Sector 9 board off of the Internet (personally my favorite brand) it's a Essential Carvin. About 2.5-3.5 feet I think. Its almost as tall as me. It has a nice ride to it, in was cruising around town with it today for about an hour. I dont know the size of the wheels or anything, I'm kind of new and the only person who I knew a lot about boards is my ex we don't talk). But anyways, what is the board best used for? And how can I make kicking easier? Thanks. p.s I'm a girl.
