The correct Answer is:
To find the average velocity of the five particles with given speeds, we can follow these steps: ### Step 1: Identify the speeds of the particles. The speeds of the five particles are given as: - Particle 1: 1 m/s - Particle 2: 2 m/s - Particle 3: 3 m/s - Particle 4: 4 m/s - Particle 5: 5 m/s ### Step 2: Calculate the total speed. To find the average speed, we first need to calculate the total speed of all the particles. We do this by adding the speeds together: \[ \text{Total Speed} = 1 + 2 + 3 + 4 + 5 \] ### Step 3: Perform the addition. Now, we perform the addition: \[ \text{Total Speed} = 1 + 2 + 3 + 4 + 5 = 15 \text{ m/s} \] ### Step 4: Count the number of particles. The number of particles is 5. ### Step 5: Calculate the average speed. The average speed is calculated by dividing the total speed by the number of particles: \[ \text{Average Speed} = \frac{\text{Total Speed}}{\text{Number of Particles}} = \frac{15}{5} \] ### Step 6: Perform the division. Now, we perform the division: \[ \text{Average Speed} = 3 \text{ m/s} \] ### Conclusion: The average velocity of the particles is 3 m/s. ---
