## Step 1The first statement is about the dependence of initial kinetic energy on the launch angle under ideal conditions. In physics, the initial kinetic energy of a projectile is given by the equation
, where
is the mass of the object and
is the velocity. This equation does not include the launch angle, which means that the initial kinetic energy does not depend on the launch angle.## Step 2The second statement is about the relationship between the launch angle and the initial speed under ideal conditions. The initial speed of a projectile is determined by the force applied to it, not the angle at which it is launched. Therefore, increasing the launch angle does not necessarily decrease the initial speed.## Step 3The third statement is about the change in horizontal velocity during the flight of a projectile. In an ideal projectile motion, the horizontal velocity remains constant because there are no horizontal forces acting on the projectile (assuming air resistance is negligible).## Step 4The fourth statement is about the relationship between the right side of the equation and the horizontal distance,
. The right side of the equation is not specified in the problem, so we cannot determine its relationship with
.
