Answer:
a) 10.54 sec
b) 284.58 m
c) 29.406 m/s
d) 39.92 m/s
Explanation:
Given data:
velocity of spacecraft = 27.0 m/s
rate of free fall acceleration is 2.79 m/s^2
distance of moving aircraft from mooon surface is 155 m
a. from kinematic eqaution of motion we have

where y = 155 m
Vi = 0 as this relation is for vertical motion, so the 27.0 m/s is not included
and a = 2.79 m/s^2.
Solving for t we get
t = 10.54 sec
b.
we know that 


c. from the kinematic formula
v = u + at

v = 29.4066 m/a
d. 
v = 39.92 m/s
Answer:
Mars.
Explanation:
It only has a little over 24 hours in a day, its rotation axis is tilted about the same as earths, and I MAY actually have some water on its surface.(Though none has been discovered YET)
Hope this helps lots and lots,
sincerely, me
