The average velocity is zero

Given:

A man leaves home for a cycle ride and comes back home after a half-an-hour rise covering a distance of 1 km.

To find:

The average velocity

• Average velocity: The change in position or displacement divided by the time intervals.

Here,

• (x₁) and (x₂) is the position of the object at the time (t₁) and (t₂) accordingly.
• (Δx) = displacement and (Δt) = time interval.

The man comes back home. So, displacement is 0 and time take = 1/2 hour

Thus, option (d) zero is correct

• The average velocity of the ride is zero

Distance = 1 km

Time taken = 0.5 hours

Displacement = 0 km

As the man comes back to home (initial position), hence the initial position and final position are same. Thus displacement is zero.
