Mars, rock fragments would have to reach its escape velocity of 5.0 km/s, and this would most likely happen over a distance of about 4.0 m during the meteor impact. (a) What would be the acceleration (in m/s² and g's) of such a rock fragment, if the accel- eration is constant? (b) How long would this acceleration last?

Question
Please, I need some assistance as to how they got their answer?
![It has been suggested, and not
facetiously, that life might have originated on Mars and been car-
ried to the earth when a meteor hit Mars and blasted pieces of rock
(perhaps containing primitive life) free of the surface. Astronomers
know that many Martian rocks have come to the earth this way.
(For information on one of these, search the Internet for “ALH
84001.") One objection to this idea is that microbes would have to
undergo an enormous lethal acceleration during the impact. Let us
investigate how large such an acceleration might be. To escape
Mars, rock fragments would have to reach its escape velocity of
5.0 km/s, and this would most likely happen over a distance of
about 4.0 m during the meteor impact. (a) What would be the
acceleration (in m/s² and g's) of such a rock fragment, if the accel-
eration is constant? (b) How long would this acceleration last?
