Question

For which of the following angles of projection, the projectite will NOT have the same range? A) 75 15⁰ (B) 30, 60° (C) 60°, 15 (D) 40, 50°
Explain ​

Answer 1

Answer:

Explanation:

Correct option is

C

100 m

The horizontal range of a projectile fixed at an angle=15°

Range=50m

In dirst case range=50=u  

2

/g(sin2×15°)

50=  

2g

2

 

​

 

g

u  

2

 

​

=100

In 2nd case range=  

g(sin2×45°)

u  

2

 

​

 

=  

1

100

​

(∵sin90°=1)

=100m
