A ball is being launched horizontally from an unknown distance above the ground Which parameter doesn't effect the range of the ball. Select one: a. Initial velocity. b. Gravitational acceleration c. Mass of the object. d. Distance from the ground.

## Step 1<br />The range of a projectile is the horizontal distance it covers from the point of projection to the point of landing. The range of a projectile is influenced by several factors.<br /><br />## Step 2<br />The initial velocity of the projectile is one of these factors. The higher the initial velocity, the farther the projectile will travel.<br /><br />## Step 3<br />The gravitational acceleration is another factor that influences the range of a projectile. The gravitational acceleration affects the vertical motion of the projectile, which in turn affects the time the projectile is in the air. This, in turn, affects the horizontal distance the projectile covers.<br /><br />## Step 4<br />The mass of the object is not a factor that affects the range of a projectile. This is because, according to the principles of classical mechanics, the mass of an object does not affect its range of motion unless air resistance is considered. In most cases, we assume that air resistance is negligible, so the mass of the object does not affect the range.<br /><br />## Step 5<br />The distance from the ground is another factor that affects the range of a projectile. The higher the distance from the ground, the longer the projectile will be in the air, and the farther it will travel.
