An airplane needs to reach a forward velocity of 203.0 km/h. To take off. On a 2000-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, we use the equation $ v^2 = u^2 + 2as $, where $ v = 203.0 \, \text{km/h} = 56.39 \, \text{m/s} $, $ u = 0 \, \text{m/s} $, 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 $.
