# Motion in two dimension problem. Range and Height.

greg_jones20

## Homework Statement

A rocket is launched from level ground with a speed of 30.0 m/s at an angle of 40 degrees above the horizontal. Find:

a) Maximum height reached by the rocket.
b) The time rocket is in the air.
c) the horizontal distance where the rocket lands.

## Homework Equations

V= Vo + at
V^2 = Vo^2 + 2a(X-Xo)
X= Xo +Vo(t) + (1/2)at^2

## The Attempt at a Solution

Divided the entire motion into two phases 1st and 2nd, Got x and y components of everything. Can't seem to find the time and final position anyway. I am not allowed to use the direct formula for Range and Height.

You'll have to show some of your work so that we'll know where to help. What are your "phases"?

greg_jones20
Well I meant the two different phases for first and second half part of its motion.

Never mind I figured out how to solve this problem.
Thanks anyway.
