An arrow is shot in air, its time of flight is 5 sec and horizontal range is 200m. The inclination of the arrow with the horizontal is-
A
tan –1 
B
tan –1 
C
tan –1 
D
45°
Text Solution
Verified by ExpertsThe correct answer is:
A
T = 5 = 
u sin θ = 25
R = 
= 200
(25) (u cos θ) = 200
u cos θ = 
= 40
tan θ = 
= 
θ = tan–1
