Question

A stone falls from rest from the top of a high tower. ignore air resistance and take g =10m/s?
a)what is it velocity after
1) 1 second, 2)2 second,
3) 3 second,
4) 5 seconds,


if u will give correct explaination i will mark as brainlist ​

Answer 1

Question:-

• A stone falls from rest from the top of a high tower. ignore air resistance and take g =10m/s. Find its velocity after 1 , 2 , 3 , 5 seconds.

To Find:-

• Find the time.

Solution:-

Given ,

• u = 0 ; g = 10m/s² ; t = 1 ; v = ?

Formula to be Used:-

$\tt \implies \: v = u + at$

Find the velocity after 1 second:-

$\tt \implies \: v = 0 + 10 \times 1$

$\tt \implies \: v = 10 \: m/s$

Find the velocity after 2 second:-

$\tt \implies \: v = 0 + 10 \times 2$

$\tt \implies \: v = 20 \: m/s$

Find the velocity after 3 second:-

$\tt \implies \: v = 0 + 10 \times 3$

$\tt \implies \: v = 30 \: m/s$

Find the velocity after 5 second:-

$\tt \implies \: v = 0 + 10 \times 5$

$\tt \implies \: v = 50 \: m/s$

Hence ,

• Velocity at 5 sec is 50 m/s

Answer 2

Answer:

Zero is the velocity of stone

Explanation:

Because when a stone falls from high tower the stone does not change in his velocity w. r. t time period
