Question

An airplane accelerates through a runway at 4.5m/s² for 40 seconds until it finally lifts off the ground. determine the distance travelled before the take off​

Answer 1

Step-by-step explanation:

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
