Question

Please answer the questions:

1. A meteor falls from the sky to the Earth. The meteor already had an initial velocity downward when it was spotted. If it hot the Earth at 335m/s after neing seen for 30 seconds, then what is the initial velocity of the meteor?

Thx!

Answer 1

Final velocity v = 335 m/s

Acceleration a = g = 9.8 m/s^2

Time t = 30 s

Initial velocity u = ?

v = u + at

Or, u = v - at

= 335 - 9.8 * 30

= 335 - 294

= 41 m/s

Ans: 41 m/s

Answer 2

335 = u + 30(9.81)

u = 40.7m/s

Answer 3

v=335m/s

u=?

acceleration =gravity that is 9.8m/s

v=u+at

t=30sec

u=at-v

9.8x30-335=

295-335+

41is the initial speed

Answer 4

This is just a guess.

Well, Given are:

       S = 335m/s

       t =  30 s

       Find- V=?

       Formula:

                V= displacement(speed and direction) divide by time

                

        solution:

                335m/s divide by 30 s.

                

         Final answer: 11.166666.. or estimated 1.6667

That's all

follow all the format and you will find the answer..

given, find, formula, solution and final answer.. good luck!!
