An engine of the orbital maneuvering system (OMS) on a space shuttle exerts a force of 2.64×104N j^ over a time interval of 4.50s , exhausting a negligible mass of fuel relative to the shuttle's mass of 9.55×104kg .
A. What is the impulse of the force for this time interval of 4.50 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?
