An aircraft starts from rest and accelerates uniformly along a runway of length 1.2 km.
It leaves the ground at a speed of 60 m/s.
Use the equation: (final velocity)2−(initial velocity)2=2×acceleration×distance(\text{final velocity})^2 - (\text{initial velocity})^2 = 2 \times \text{acceleration} \times \text{distance}(final velocity)2−(initial velocity)2=2×acceleration×distance
What is the acceleration of the aircraft?
