A jet plane is cruising at 300 m/s when suddenly the pilot urns the engines up to full throttle. After traveling 4.0 km, the jet s moving with a speed of 400 m/s. What is the jet’s acceleration,
assuming it to be a constant acceleration?

physics are blehhhh

fanduekisses · Answer

oh ok but in this case the change in velocity is 100 m/s?

agent0smith · Answer

$$\Large v^2 =v_o ^2 +2a x$$

final speed v, initial vo
acceleration a, distance x

Make sure you use m not km.
