Question 1185867: A meteor falls from the sky to the Earth. The meteor already had an initial velocity downward when it was spotted. If it hit the Earth at 335 m/s after being seen for 30 seconds, what was the initial velocity of the meteor?

.

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.
