Understanding the Components
* Horizontal Component (Vx): This component remains constant throughout the flight (assuming no air resistance). It's calculated as:
Vx = V * cos(theta), where:
* V is the initial velocity of the rock.
* theta is the launch angle (50 degrees).
* Vertical Component (Vy): This component changes as the rock moves upward. It's affected by gravity. At the highest point of the trajectory, Vy becomes zero for a brief moment. It's calculated as:
Vy = V * sin(theta) - g*t, where:
* g is the acceleration due to gravity (approximately 9.8 m/s²)
* t is the time elapsed since the throw.
As the Rock Rises
* Horizontal Velocity (Vx): Stays the same, as explained above.
* Vertical Velocity (Vy): Decreases. Gravity acts downward, slowing the upward motion of the rock.
At the Highest Point
* Horizontal Velocity (Vx): Remains constant.
* Vertical Velocity (Vy): Becomes zero. The rock momentarily stops moving upward before it starts to fall back down.
Key Points
* Air Resistance: This explanation assumes no air resistance. In reality, air resistance would affect both components of the velocity, making the calculations more complex.
* Projectile Motion: This is a classic example of projectile motion, where an object is launched into the air and follows a parabolic path.
Let me know if you'd like to calculate the components of the velocity at a specific time during the flight!
