Answer:
The minimum time of flight for the ball is 16.38 s
Explanation:
Projectile Motion: When we throw an object which make an angle with horizontal and only one acceleration which work on that object that is acceleration due to gravity. This type of motion is known as projectile motion.
Range: The distance is covered horizontally by the object is known as Range of the object.
u = initial velocity= 200m/s
g = acceleration due to gravity = 9.8m/s²
θ= angle
R= range = 3.0 km= 3000 m
⇒θ= 23.65°
Flight time
s
The minimum time of flight for the ball is 16.38 s
