Question

A stone falls from rest from the top of a high tower. ignore air resistance and take g =10m/s?
b) how far has it fallen after
a) 1seconds
b) 2seconds
c) 3 seconds
d) 5seconds
who will say correct explaination and answer I will mark as brainlist​

Answer 1

Answer:

I think d

Explanation:

i just guessed.

Answer 2

Answer:

I think its( d) 5 sec as

Explanation:

Let’s visualize this without writing any equations. As g is constant, the velocity increases uniformly; that is, the graph of velocity versus time is a straight line. The velocity is zero when the time is zero (because the stone falls from rest). The velocity increases by 10m/s every second, which means it is 10m/s after the first second. Because the graph of velocity is a straight line, the average velocity during the first second is half the final velocity, or 5m/s. Therefore the stone has fallen 5 meters after 1 second.
