An aircraft travels along a straight runway. Its velocity increases uniformly from 36 km/h to 108 km/h in 8.0 s.
Which comparison is correct for the acceleration of the aircraft and the acceleration of free fall?
Use g=10 m/s2g=10\ \mathrm{m/s^2}g=10 m/s2.
The acceleration of free fall is 1.11.11.1 times the acceleration of the aircraft.
The acceleration of free fall is 0.250.250.25 times the acceleration of the aircraft.
The acceleration of free fall is 4.04.04.0 times the acceleration of the aircraft.
The acceleration of free fall is 2.72.72.7 times the acceleration of the aircraft.
