Horizontal Motion:

* Constant Velocity: Since there's no horizontal force acting on the ball (ignoring air resistance), it will continue moving horizontally at a constant 8 meters per second.

* Horizontal Displacement: The ball will have traveled 8 meters horizontally in one second (8 m/s * 1 s = 8 m).

Vertical Motion:

* Acceleration due to Gravity: The only force acting on the ball vertically is gravity, which causes a downward acceleration of approximately 9.8 m/s².

* Vertical Velocity: After one second, the ball will have gained a downward velocity of 9.8 m/s (9.8 m/s² * 1 s = 9.8 m/s).

* Vertical Displacement: The ball will have fallen a distance of 4.9 meters (using the equation d = 1/2 * a * t², where d is distance, a is acceleration, and t is time).

Summary:

One second after being thrown, the ball will have:

* Horizontal Velocity: 8 m/s

* Vertical Velocity: 9.8 m/s downwards

* Horizontal Displacement: 8 meters

* Vertical Displacement: 4.9 meters downwards
