An engine of the orbital maneuvering system (OMS) on a
space shuttle exerts a force of for 3.90 s, exhausting
a negligible mass of fuel relative to the 95,000-kg mass of the
shuttle. (a) What is the impulse of the force for this 3.90 s? (b)
What is the shuttle’s change in momentum from this impulse?
(c) What is the shuttle’s change in velocity from this impulse?
(d) Why can’t we find the resulting change in the kinetic energy of
the shuttle?
