Asoccer ball is kicked from point pi at an angle above a horizontal field. the ball follows an ideal path before landing on the field at point pf . which of the following statements is true when the ball is at point x?
a. the horizontal velocity vector points to the right & equals v cos î¸.
b. the vertical velocity points up & equals v sin î¸.
c. the acceleration vector points up.
d. the total velocity equals the initial velocity v.

A. The horizontal velocity vector points to the right & equals v cos θ.

Explanation:

The motion describes a parabolic path, where the horizontal speed is constant and the horizontal velocity vector always points to the right and equals v*cos θ.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
