Question

A bol is released from a height of 1 meter. What time it will take to reach the surface of the earth?​

Answer 1

Step-by-step explanation:

Let the value of g be 10m/s²

Now

We know that,

v=u +at

v=0+10t (u=0 , as it is released from rest)

v=10t————eq 1

Now

v²=u²+2as

(10t)²=0+2*10*s. (using eq 1)

100t²=20——-(s=1m)

t=√(20/100)

t=√0.2 sec

hope it is helpful dear friend
