(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A rocket is intially at rest on the ground when its engines are fired the rocket flies off in a straight line at an angle of 53.1 degrees abovie the horizontal with a constant acceleration of magnitute g, the engines stop at time T after launch after which the rocket is a projectile Ignore air resistance and assume g is independant of altitude

C) Find the max altitude reached by the rocket andswer in terms of g and T

D) Find the horizontal distance from the launch point to where the rocket hits the ground answer in terms of g and T

(already got A and B CD are the last two)

2. Relevant equations

Im thinking that you use

y= 1/2gt^2 + Voyt+ Yo

3. The attempt at a solution

y=1/2gt^2 + Voyt+ Yo

y= 1/2 .8gT^2+0T+0

y=1/2 .8gT^2

now i got the .8 from using Voy=vsin53.1 is that correct?

and then after all that I just added that equation to the distance from when the rockets turned off the engines to when the verticle velocity would = 0... can someone please do this problem and explain in detail the best you can for each step and why you did it, i dont even know where to start with D
