The initial speed of a cannon ball is 200 m/s. If the ball is to strike a target that is at a horizontal distance of 3.0 km from the cannon, what is the minimum time of flight for the ball

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

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
