Question 62

An aircraft touches down on a straight runway. It slows with uniform acceleration.

time after touchdown in s\mathrm{s}svelocity in m/s\mathrm{m/s}m/s
0.068
8.044

The aircraft continues to slow with the same acceleration until its velocity is 20 m/s.

Use the equation

v2−u2=2ax v^2-u^2=2ax v2−u2=2ax

Calculate the distance travelled by the aircraft from touchdown until its velocity reaches 20 m/s.
