Suppose a boat is moving 6m/s relative to the pier, but you are walking on the boat -1 m/s relative to the boat' What would be your relative velocity to the pier? What direction would the boat be moving? Is this a one or two-dimensional problem?

V₁ = 5 m/s

This is the problem of one dimension

Explanation:

Before using the concepts of relative velocity, we must first define the variables for each velocity here:

V₁ = Person's Velocity Relative to Pier = ?

V₂ = Boat's Velocity Relative to Pier = 6 m/s

V₁₂ = Person's Velocity Relative to Boat = - 1 m/s

Now, from the relative velocity, we know that:

V₁₂ = V₁ - V₂

- 1 m/s = V₁ - 6 m/s

V₁ = 6 m/s - 1 m/s

V₁ = 5 m/s

This is the problem of one dimension

because, the velocity is along single dimension with opposite directions. No, second dimension is involved.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
