Question : A projectile shot into air at some angle with the horizontal has a range of 200 m. If the time of flight is 5 s, then the horizontal component of the velocity of the projectile at the highest point of trajectory is

(A) $40ms^{-1}$

(B) $0ms^{-1}$

(D) Equal to the velocity of projection of the projectile

Answer : option (A)

Solution :

A projectile shot into air at some angle with the horizontal has a range of 200 m. If the time of flight is 5 s, then the horizontal component of the velocity of the projectile at the highest point of trajectory is
