Finding Fx when the angle doesn't create a right angle

[Aladdinnas]

Why is physics so confusing?

Hey, it's my first time here...cz i need serious help.
My teacher gave us a review sheet for a big test, and he expects me to do it, even knowing that i jus moved into this class...
I've got most of the notes...but i still find things confusing...


For Question#1

Fnet = Fg-Fn
=(-5.586x10(p6))+(1.5x10(p7))
=9.414x10(p6)
F=ma
=29.4x5.7x10(p5)
=1.6758x10(p7)
I understand the concept so far...but since the angle will NOT create a right angle, i need to find another method of getting Fx.

here is the question

1. During a space shuttle flight, an acceleration upward of 29.4m/s2[Y15X] is measured. Assuming that the shuttle has a mass of 570000kg, calculate the force that the small maneuvering thrusters would have to fire at to accomplish this. The main engines provide a force of 15000000N [Y] upward.

opps...i jus realized...this dosent belong in this forum...it's needs to be sent to the homework help forum
