Question

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

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

Answer 1

Answer: (D)

In two dimensional motion, if instantaneous speed is a positive constant then equal path lengths are traversed in equal intervals of time.
