Answer 1

Answer:

Hello mate,

Explanation:

(a)Does not represent motion in one dimension because

a particle cannot have two different speeds at a time.

(As far as not considering the weirdness of quantum world.)

(b)Does not represent motion one dimension because speed=distance/time.So as time goes the distance covered by a body cannot decrease it will only increase if the particle is moving ,but displacement can decrease.

Hope the qn is answered
