Kinematics_5 (Constant Non-Zero Acceleration)

Описание к видео Kinematics_5 (Constant Non-Zero Acceleration)

On its takeoff roll, the airplane starts from rest and accelerates according to a = ao, where ao is the constant acceleration resulting from the engine thrust. If ao = 2 m/s2,

determine the design length of runway required for the airplane to reach the takeoff speed of 250 km/h.
determine the time required to reach takeoff speed.
determine the ratio: 𝑑(𝑡=0 →1 𝑠)= ? 𝑑(𝑡=0 →3 𝑠)
determine the ratio: 𝑑(𝑡=2 →4 𝑠)= ? 𝑑(𝑡=2 →4 𝑠)
determine the ratio: 𝑠_𝑎𝑣𝑔 (𝑡=2 →4 𝑠)=? 𝑠_𝑎𝑣𝑔 (𝑡=3 →6 𝑠)
determine the ratio: Δv(t = 1 → 3 s) = ____ Δ v(t = 2 → 6 s).
TRUE or FALSE: The average speed savg during each second increases as the airplane accelerates.
