#588253 — Orbital Physics Question

Initially, a small satellite is in a circular orbit about mars. Over a 
very small time interval, an external force accelerates the satellite in 
the direction of the satellite’s velocity vector. After the impulse is 
applied, the satellite is in a new orbit (which is still bound). Which 
of the following statements is NOT true?

a) There was an increase in the angular momentum of the satellite about 
the center of mass of Mars.
b) The eccentricity of the new orbit is less than one.
c) After the impulse is applied, the speed of the satellite will change 
throughout the new orbit.
d) The period of the new orbit is shorter than the period of the 
original orbit.
e) The total energy of the satellite after the impulse is applied is 
larger than the initial total energy of the
satellite.

All 4 posts look like the homework or exam test questions...

yup, I think from GRE,
one or two did not have answer listed, this question should be easy...
