To find the relative acceleration of the second particle with respect to the first, we need to analyze the motion of both particles as they slide down the inclined wires. Since both particles start from the same point and slide down at different angles, we can use basic physics principles to determine their accelerations and then find the relative acceleration.
Understanding the Setup
We have two particles:
- Particle 1 slides down a wire inclined at 30 degrees to the vertical.
- Particle 2 slides down a wire inclined at 60 degrees to the vertical.
Both wires are smooth, meaning there is no friction acting on the particles. The only force acting on each particle is gravity, which we can break down into components along the incline.
Calculating the Acceleration of Each Particle
The acceleration of an object sliding down an incline can be determined using the formula:
a = g * sin(θ)
where:
- a is the acceleration along the incline,
- g is the acceleration due to gravity (approximately 9.81 m/s²),
- θ is the angle of the incline.
Acceleration of Particle 1
For Particle 1, which is inclined at 30 degrees:
a₁ = g * sin(30°)
Since sin(30°) = 0.5, we have:
a₁ = g * 0.5 = 0.5g
Acceleration of Particle 2
For Particle 2, which is inclined at 60 degrees:
a₂ = g * sin(60°)
Since sin(60°) = √3/2, we have:
a₂ = g * (√3/2)
Finding the Relative Acceleration
The relative acceleration of Particle 2 with respect to Particle 1 is given by:
a_relative = a₂ - a₁
Substituting the values we calculated:
a_relative = g * (√3/2) - 0.5g
Factoring out g gives us:
a_relative = g * (√3/2 - 0.5)
Calculating the Numerical Value
To find the numerical value, we can use the approximate value of g (9.81 m/s²):
a_relative = 9.81 * (√3/2 - 0.5)
Calculating √3/2 gives approximately 0.866, so:
a_relative = 9.81 * (0.866 - 0.5)
a_relative = 9.81 * 0.366
a_relative ≈ 3.60 m/s²
Final Thoughts
The magnitude of the relative acceleration of the second particle with respect to the first is approximately 3.60 m/s². This result shows how the different angles of inclination affect the acceleration of each particle as they slide down their respective wires. Understanding these principles can help in analyzing more complex motion scenarios in physics.
