An airplane needs to reach a forward velocity of $203.0 \mathrm {~km} / \mathrm { h }$ to take off. On a $2000 - \mathrm { m }$ runway, what is the minimum uniform acceleration necessary for the plane to take flight if it starts from rest? A) 0.79 m/s² B) 0.87 m/s² C) 0.95 m/s² D) 1.0 m/s²

To find the minimum uniform acceleration, use the equation $v^2 = u^2 + 2as$, where $v = 203.0 \, \text{km/h} = 56.39 \, \text{m/s}$, $u = 0$, and $s = 2000 \, \text{m}$. Solving for $a$, we get $a = \frac{v^2}{2s} = \frac{(56.39)^2}{2 \times 2000} \approx 0.79 \, \text{m/s}^2$.
