1. Understand the Physics
* Projectile Motion: The soccer ball's motion is a projectile, meaning it's influenced by gravity. We need to consider both horizontal and vertical components of its motion.
* Horizontal Velocity: The horizontal velocity remains constant throughout the flight.
* Vertical Velocity: The vertical velocity is affected by gravity, slowing down as the ball rises and speeding up as it falls.
2. Break Down the Initial Velocity
* Horizontal Component (Vx): Vx = V * cos(theta) = 26 m/s * cos(30°) ≈ 22.5 m/s
* Vertical Component (Vy): Vy = V * sin(theta) = 26 m/s * sin(30°) = 13 m/s
3. Calculate the Time of Flight
* Symmetry: The time it takes for the ball to go up is equal to the time it takes to come down.
* Vertical Motion: We can use the following kinematic equation:
Vyf = Vy + at, where:
* Vyf = final vertical velocity (0 m/s at the highest point)
* Vy = initial vertical velocity (13 m/s)
* a = acceleration due to gravity (-9.8 m/s²)
* t = time
* Solving for t: 0 = 13 - 9.8t
t ≈ 1.33 s (This is the time to reach the highest point, double it for the total time of flight)
Total time of flight ≈ 2.66 s
4. Calculate the Horizontal Distance (Range)
* Range: Range = Horizontal Velocity * Time of flight
* Range: Range ≈ 22.5 m/s * 2.66 s ≈ 59.85 m
Answer: The soccer ball travels approximately 60 meters before hitting the ground.
