Question

If the velocity $upsilon$ of a particle moving along a straight line and its distance $s$ from a fixed point on the line are related by $upsilon to the power of 2 end exponent equals a to the power of 2 end exponent plus s to the power of 2 end exponent comma$ then its acceleration equals

$a s$
$s$
$s^{2}$
$2 s$

The correct answer is: $s$

We have,
$upsilon to the power of 2 end exponent equals a to the power of 2 end exponent plus s to the power of 2 end exponent$
