Question

Which of the following is largest when the height attained by the projectile is the largest​

Answer 1

Explanation:

Maximum height attained by the projectile is largest when, θ=90

∘

Wkt that R=

g

v

2

sin2θ

and here θ=90

∘

∴sin2θ=0 and R=0

Now, T=time of flight =

g

2vsinθ

and here θ=90

∘

so sin90

∘

=1

So, Time of flight will be maximum.
