Question

which of the following is largest when the height attained by the projectile is greatest
1- Range
2- Time of flight
3- Angle of projectile with vertical
4- Acceleration ​

Answer 1

Answer:

time of flight

Explanation:

ANSWER

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.
