What is a hafted projectile?
A hafted projectile is a projectile, such as a stone arrowhead or spear point, that is attached to a handle or shaft to increase its effectiveness as a weapon. By combining the projectile with a handle, the weapon becomes more accurate, can be thrown or launched further, and can be used multiple times.
What is the direction of oblique projectile at highest point?
At the highest point of its trajectory, the direction of an oblique projectile will be horizontal. This means that the projectile will momentarily have zero vertical velocity and only horizontal velocity.
The path of motion of a thrown javelin is an example of motion (1 point)?
Projectile.
What is the speed of a projectile equal to at its highest point?
At the highest point of its trajectory, the speed of a projectile is equal to zero as it momentarily stops before starting to descend.
What is the vertical velocity of a projectile at the lowest point in trajectory?
The vertical velocity of a projectile at the lowest point in its trajectory is zero. This occurs because at that point, the projectile has reached the maximum height and is momentarily stationary before it starts descending.
What quantities are zero throughout the flight of a projectile?
The vertical velocity at the highest point of the trajectory, the vertical displacement when the projectile returns to its initial height, and the vertical acceleration at the highest point are all zero throughout the flight of a projectile.
Which was the first stone tool made by man?
projectile pointed chert and flint
Where did the stone age get its name?
Humans had learned to make tools of chipped stone, but had not yet learned to make them from metals.
What is the value of the vertical speed at the highest point of the projectile's trajectory?
The vertical speed at the highest point of a projectile's trajectory is zero. This is because at the peak of the trajectory, the projectile momentarily stops ascending and starts descending, resulting in a velocity of zero in the vertical direction.
What are the two components of a projectile?
The two components of a projectile are the horizontal component, which determines the distance the projectile travels, and the vertical component, which influences the projectile's height and the time it takes to reach the highest point and return to the ground.
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 are some Stone Age implements?
Choppers, grinding stones, knives, projectile points
