Question 1
An air-plane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance travelled before take off.​

Answer 1

Answer:

Initial speed of airplane u=0 m/s

Acceleration of the plane a=3.2 m/s

2

and time taken t=3.28 s

Using formula, distance covered S=ut+
