Step-by-step explanation:
The average velocity of a particle in straight line motion over a given finite time interval can be determined by dividing the displacement of the particle by the time taken. Mathematically, the average velocity (v_avg) is calculated using the formula:
v_avg = Δx / Δt
where:
v_avg represents the average velocity
Δx denotes the change in position or displacement of the particle
Δt represents the change in time or the time interval over which the displacement occurred.
By dividing the change in position by the change in time, we obtain the average velocity of the particle. It provides an indication of the average speed and direction of the particle over the given time interval
