Radio Control Short Course
I cant get this and its due very soonn pleasee helpp?
A(n) 6900 kg rocket traveling at 3700 m/s is
moving freely through space on a journey to
the moon. The ground controllers find that
the rocket has drifted off course and that it
must change direction by 12◦ if it is to hit the
moon. By radio control, the rocket’s engines
are fired instantaneously (i.e., as a single pel-
let) in a direction perpendicular to that of the
rocket’s motion. The gases are expelled (i.e.,
the pellet) at a speed of 4900 m/s (relative to
the rocket).
What mass of gas must be expelled to make
the needed course correction? Answer in units
of kg.
In the realistic world, the gas is not exhausted
in one short burst as a single gas pellet. The
gas is released over a time span in molecular
form.
Assume: The mass of the gas is much less
than the mass of the rocket.
In the realistic situation, what mass of gas
must be expelled to make the needed course
correction? Answer in units of kg.
wow… now i know what to expect in hs/college. i lost you after the 1st few sentences.
