Question

An aeroplane accelerates down a runway at 3.20 m/s2 for 32.8 sec until it is
finally lifts off the ground. Determine the distance travelled before take off.
1) 1520m
2) 1721.34m
3) 104.96m
4) 1049.6m
with explanation​

Answer 1

Answer:

1721.34

Initial speed of airplane  u=0 m/s

Acceleration of the plane  a=3.2 m/s2 and time taken t=3.28 s

Using formula, distance covered S=ut+21at2  

⇒   S=0(32.8)+0.5(3.2)(32.8)2=1721.3∼1720m
