If net acceleration is not equal to 0 :)

possibly, because of air drag

When jumping from a trampoline on a moving trailer into a pool:

Key Factors

1. Horizontal velocity: The person shares the trailer's velocity.

2. Vertical velocity: Upward velocity from the trampoline jump.

3. Air resistance: Affects horizontal motion.

4. Trailer's acceleration/deceleration: Impacts landing position.

5. Trampoline's vertical velocity: Adds to the jump.

Trajectory

1. The person's horizontal velocity remains relatively constant.

2. Vertical velocity decreases due to gravity.

3. The person follows a curved trajectory.

Landing

1. Pool position: Depends on trailer speed, trampoline height and jump velocity.

2. Horizontal displacement: Person lands ahead of the trampoline due to trailer's forward motion.

3. Vertical displacement: Person enters the pool at an angle.

Real-World Considerations

1. Air resistance slows horizontal motion.

2. Trailer's acceleration/deceleration alters landing position.

3. Pool size and shape affect landing safety.

4. Jump timing and technique influence trajectory.

Physics Equations

1. Horizontal motion: x = v₀t

2. Vertical motion: y = v₀t - (1/2)gt²

3. Trajectory: y = tan(θ)x - (g/2v₀²cos²(θ))x²

Safety

1. Ensure proper trampoline safety measures.

2. Calculate jump velocity and trajectory.

3. Consider trailer speed and acceleration.

4. Designate a safe landing zone.
