Question

if range of projectile fired at 30 degree with horizontal is 50m . The range of same projectile fired ss 10 degree with horizontal will be?​

Answer 1

Answer:

The range of the projectile motion R=

g

u

2

sin2θ

I case

⇒ θ=15

⇒ 50=

10

u

2

sin30

⇒ u

2

=1000 .. eq(1)

II case

u^2 =1000 , θ=45

⇒ R=

10

u

2

sin90

=

10

1000

=100m

hence the C option is correct
