As per your syllabus, what is INSTANTANEOUS SPEED equal to (in MAGNITUDE) — at a given instant?
AThe square of velocity
BThe magnitude of the instantaneous velocity at that instant
CHalf of velocity
DAverage speed
Answer & Solution
Correct answer: B. The magnitude of the instantaneous velocity at that instant
As per your syllabus, at a single instant, speed = |velocity|.
*Note: only for FINITE intervals does avg speed differ from |avg velocity|.*
