Question

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, then what was the initial
velocity of the meteor?
a=9.8

Answer 1

The initial velocity of the meteor was 41 m/s.

Step-by-step explanation:

To find the initial velocity of the meteor, we can use the equation of motion:

v = u + at

Given that the meteor hits the Earth with a final velocity of 335 m/s after being seen for 30 seconds, we can substitute the values:

335 = u + 9.8 x 30

Simplifying the equation, we get:

u = 335 - 9.8 x 30

u = 335 - 294

u = 41 m/s

Therefore, the initial velocity of the meteor was 41 m/s.
