I know that the minimum speed is at the heighest point when the x axis is 0 because no gravity is acting on it. And i know you are supposed to use this formula xcosa but i dont understand why? Please help exam soon!!!!

At what part of the trajectory does a projectile have minimum speed?
A projectile has minimum speed at the top of the trajectory.
At what part of a path does a projectile have minimum speed?
The projectile have minimum speed when it is in top of prabolic and it have max sped when it is in intial point
On what does the range of a projectile depend?
The speed and direction of the wind and the elevation of the machine firing the projectile. If the machine is pointing straight up, the projectile will not go very far. If it is pointing at the right elevation, the projectile will go farther.
At what point or points in its path does a projectile have its minimum speed and its maximum?
Let us try and answer this quest by using a bullet or shell fired from a gun. The projectiles maximum speed is at the point of leaving its casing. From that moment it begins to be slowed by air pressure in front of the projectile and also curves towards the earth attracted by gravity. Point of interest. The rifling of a guns barrel does not make the projectile go faster. It makes it spin so that it travels straighter and not tumble like the old none spinning projectiles.
What can be a sentence for projectile?
They were shooting projectile out of their guns.
At what part of the trajectory does a projectile have minimum speed?
A projectile has minimum speed at the top of the trajectory.
At what part of a path does a projectile have minimum speed?
The projectile have minimum speed when it is in top of prabolic and it have max sped when it is in intial point
What is the minimum speed for a projectile to go in orbit?
Depends on mass and surface area
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
8km/s
What is the value of the vertical speed at the highest point of the projectile's trajectory?
The value of the vertical speed at the highest point of the projectile's trajectory is the lowest speed at the maximum height reached.
What is maximum momentum and minimum momentum in projectile motion?
You are wrong
With out air pressure at what point or points in its path does a projectile have its minimum speed and its maximum?
Without air friction, the horizontal component of the velocity will be constant. The vertical component of the velocity will be a maximum at the lowest point in its motion and at a minimum at the highest point in its motion. Therefore the minimum is at the highest point in its motion- Potential energy max Kinetic Energy min and the maximum is at its lowest point in the motion- KE is max PE min
What is the vertical speed of a projectile at the top of its flight?
Zero.
How can you throw a projectile so that it has nonzero speed at the top of trajectory?
If the projectile's velocity has a horizontal component - in other words, it doesn't go straight up - then its speed will never be zero.
On what does the range of a projectile depend?
The speed and direction of the wind and the elevation of the machine firing the projectile. If the machine is pointing straight up, the projectile will not go very far. If it is pointing at the right elevation, the projectile will go farther.
Was The minie ball the first projectile to combine the speed and accuracy with the loading speed of a smoothbore rifle?
No
Speed of projectile as it leaves a firearm?
Known as the muzzle velocity, it is the fastest speed the bullet will have in flight.
