.


In this problem, we consider the Earth as an unmoving object and consider the meteor as the body 


falling downward to the Earth with uniform constant gravity acceleration g = 10 m/s^2.



Due to gravity, the meteor will gain the speed   10*30 = 300 m/s  during 30 seconds.


So, vertical speed of the meteor relative the Earth 35 seconds before hitting ground is  335 - 300 = 35 m/sec.
