A particle moving with uniform acceleration has its final velocity

(v = \sqrt {150 + 8x} )\,\,m\mathrm{/}s

where

x

is the distance travelled by the body then the acceleration

View answer and explanation

Correct option: B

4\,\,m\mathrm{/}{s^2}

Option B (

4\,\,m\mathrm{/}{s^2}

) is correct because it is derived by differentiating the given velocity equation with respect to x and using the chain rule.
