An object is moving with an initial velocity of 10 m/s. If it is decelerating at 2 m/s², how far does it travel before it stops? A) 15 m B) 25 m C) 35 m D) 45 m

The object stops when its final velocity is 0 m/s. Using the equation $v^2 = u^2 + 2as$, where $v = 0$, $u = 10$ m/s, $a = -2$ m/s², and $s$ is the distance, we solve for $s$: $0 = 10^2 + 2(-2)s$, which simplifies to $s = 25$ m.
