Question
A(n) 6700 kg rocket traveling at2500 m/sis
moving freely through space on ajourney to
the moon. The ground controllersfind that
the rocket has drifted offcourse and that it
must change direction by10? if it isto hit the
moon. By radio control therocket’s engines
are fired instantaneously(i.e., as asingle pel-
let) in a directionperpendicular to that of the
rocket’s motion. The gasesare expelled (i.e.,
the pellet) at a speed of 4300m/s (relativeto
the rocket).
What mass of gas must beexpelled to make
the needed course correction?Answer in units
of kg.
