I have no idea where to start with this...I know you have x and y components of something but I don't know what to do...any help in the right direction would be appreciated.

**bobpursley**, Tuesday, October 28, 2008 at 10:42pm:You have to figure the time it took to fall 3m. It had an initial vertical velocity downward of -6sin15.

h=vi*t -4.9t^2

solve for t.

Then, you know the intial horizontal velocity is 6cos15, and the time, so what distance did it travel horizontally?

**Confused**, Tuesday, October 28, 2008 at 10:51pmYou can't solve for t from that though can you? If you use quadratic equation its a negative sign under the root and you can't take the root of that. I'm confused:S
