Question

If a body travels in a uniform velocity then what will be the displacement ? (1)zero (2)+ve (3) - ve (4) all of these

Answer 1

(4) All of these.

Explanation:

Kinematic expression for displacement is

`vecs=vecs_0+vecut+1/2vecat^2`

For constant velovity it reduces to

`vecs=vecs_0+vecut`

`vecs` can be `0 or +ve or -ve` depending on direction of `vecu` and time `t`.
