The document describes the acceleration of an airplane during takeoff. It gives the acceleration function as a(t)1 = 2400 km/h^2. It uses antidifferentiation to find the velocity function v(t)1 = 2400t + C, and plugs in the initial velocity of 60 km/h to solve for the constant C = 60. This provides the full velocity function that can then be used to calculate the airplane's position over time during takeoff.
