Homework Statement
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)
Homework Equations
Im thinking that you use
y= 1/2gt^2 + Voyt+ Yo
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 don't even know where to start with D
