Question

A body is projected at an angle O with horizontal,
another body is projected with the same speed at
an angle O with the vertical then the ratio of the
maximum height is :-
(1)1:1
(2) tan²0 : 1
(3) 1 : cote
(4) none of these​

Answer 1

Answer:

1:cote

Explanation:

Let time of first and second projectiles are t  

1

​

 and t  

2

​

 respectively.

t  

1

​

=  

g

2usinθ

​

 

t  

2

​

=  

g

2usin(90−θ)

​

=  

g

2ucosθ

​

 

t  

2

​

 

t  

1

​

 

​

=  

g

2ucosθ

​

 

g

2usinθ

​

 

​

=  

cosθ

sinθ

​

=  

cotθ
