Projectiles dealing with a bullet

[gotpink74]

1. Homework Statement
A shell is fired from the ground with an initial speed of 1.60*10^3m/s at an initial angle of 56° to the horizontal.
(a) Neglecting air resistance, find the shell's horizontal range.

(b) Find the amount of time the shell is in motion.

Homework Equations

vector triangle sin and cosine

The Attempt at a Solution

all of my answers have been wrong i did the triangle and got hyp 1600 opp side 1326.46 bottom 894.7 from there i don't know where to go please HELP

You'll need to use the kinematic equations for projectile motion (horizontal and vertical components).

 

[gotpink74]

i know that i just can't figure out the horiz and vertical components is
vertical
Vi:1600
thats all i know

Would be better to:

1) Resolve the horizontal by doing Cos (theta) x initial velocity
2) v=u+at to get time in the air
3) Get horizontal component with trig like in 1)
4) distance bullet traveled is s = d / t rearranged to give d = s x t

That's all I can give you without giving you the answer on a plate :L
