##### 1 Answer

#### Answer

#### Answer:

#### Explanation

#### Explanation:

If the body is thrown up with a velocity of

we can say,

Or,

and,

Or,

or,

Now, when it comes down,if it achieves a velocity of

**CLEARLY THE BODY RETURNS TO GROUND WITH THE SAME VELOCITY WITH WHICH IT WAS PROJECTED AS WE GOT BOTH #v=u=sqrt(2gh)#**

Again,if during coming down,it takes a time of

So,time of flight (

Given,

So,putting the value we get,

**REMEMBER-when a body is thrown up with velocity #u#,total time of flight is expressed as #(2u)/g#**
