A block of ice of mass m=1.2kg is released from rest at the top of an inclined plane that makes an angle of 15 degrees with respect to the horizontal. After it slides (with negligible friction) down the plane by a distance d=0.8 m, how fast is the ice block traveling?

B) from the free body diagram, calculate the magnitude of the net force acting on it.

Don't forget to click the bump button when too many questions are on top of yours so people can see & answer your question! :p
I'm going to try and help you with this, but I want to refer you to some great Physics tutors on here, in case I'm not online when you need help: @AllTehMaffs @douglaswinslowcooper  @shamil98 (:

So this is the drawing I came up with from the info you have:|dw:1387506630417:dw|

@Kainui and @Loser66 are pretty good with physics too if I recall correctly.

So now let's add the x and y components of W (weight):|dw:1387508327575:dw|Now we need to use the formula for Fx to answer:$$\Sigma Fx=F_A-W_x=ma$$
Ok guys, help me out here... I don't think I've got the right formula...
