An airbus a380 airliner can takeoff when its speed reaches 80 m/s. suppose its engines together can produce an acceleration of 3 m/s. (a) how long does it take the plane to accelerate from 0 m/s to 80 m/s? (b) what is the distance traveled during this period?

(a). The time is 26.67 sec.

(b). The distance traveled during this period is 1066.9 m.

Explanation:

Given that,

Speed = 80 m/s

Acceleration = 3 m/s

Initial velocity = 0

(a). We need to calculate the time

Using equation of motion

Put the value into the formula

The time is 26.67 sec.

(b). We need to calculate the distance traveled during this period

Using equation of motion

The distance traveled during this period is 1066.9 m.

Hence, This is the required solution.
