12. ball being kicked by a foot and rising at an angle of 30.. from the horizontal. The
ball has an initial velocity of 5.0 m/s (Neglect friction). What is the magnitude of
the horizontal component of the balls initial velocity?
(a) 5m/s (b) 7m/s (c) 4.3m/s (d) 5.1 m/s

Answer:
Divide Displacement by Time
Divide the horizontal displacement by time to find the horizontal velocity. In the example, Vx = 4 meters per second.
Explanation:
If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both a horizontal and a vertical component. The horizontal velocity component (vx) describes the influence of the velocity in displacing the projectile horizontally.
