The instantaneous velocity at point B on this -vs- curve is best found from
The value of at B.
The slope of the <strong>tangent line</strong> at B.
The area under the curve up to B.
The slope of the chord from origin to B.
Explanation
Instantaneous velocity is the slope of the tangent (derivative) at that point. The chord-slope gives <strong>average</strong> velocity over an interval, not instantaneous.
