Question

In a two-dimensional motion, instantaneous speed 𝑣 is a positive constant. Then $v_0$
which of the following are necessarily true?

• A. Average acceleration must always vanish.
• B. Equal path lengths are traversed in equal intervals
• C. Displacements in equal time intervals are equal.
• D. The average velocity is not zero at any time

Answer 1

The correct option is B Equal path lengths are traversed in equal intervals

As we know,
$\text{Speed}=\frac{\text{distance}}{\text{time}}$

Therefore,
In two-dimensional motion, if instantaneous speed is a positive constant, then Quantitively, instantaneous speed=speed

So, equal path lengths are traversed in equal intervals of time.

Final Answer: (d) Equal path lengths are traversed in equal intervals
