Question

If the s – t graph of a particle is parallel to the t – axis, the speed of the particle is (a) zero (b) constant (c) infinite (d) non-uniform

Answer 1

zero

Step-by-step explanation:

if the velocity time graph is parallel to the time axis its mean body has not covered the path in other words body is at rest.So the velocity of the body should be zero

so the speed is zero

hope my answer will help u

Answer 2

(b) constant

Step-by-step explanation:

parallel to t - axis means, at all the times, the s component does not change, it remains same, i. e., the speed is constant.
