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 unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
