Question

The displacement x of a particle at any instant is related to its velocity as v=root2x+9. Its displacement in 2s is

Answer 1

Answer:

At any instant, the initial velocity 'u' is 0

Explanation:

At any instant, the initial velocity 'u' is 0

So, v = u + at eqn will give you the acceleration(a)

then, u can find displacement(s) using formula:‐

• s = ut –1/2 at²

Answer 2

Answer:

Δ first one is correct
