5. Assuming a constant acceleration of a = 4.3 m/s for an airplane starting from rest, how far down the runway has this airplane moved after 18 seconds it takes off?

Answer :

The distance covered by an airplane starting from rest, assuming a constant acceleration of a = 4.3 m/s and taking off after 18 seconds is 696.6 meters.

The formula for the distance covered by an object starting from rest and assuming a constant acceleration is:

s = (1/2) * a * t² Where;

  • s is the distance covered
  • a is the constant acceleration
  • t is the time taken

Substituting the given values into the formula above;

s = (1/2) * a * t² = (1/2) * 4.3 m/s² * (18 s)²

s = 696.6 meters

Therefore, the airplane has moved 696.6 meters down the runway after 18 seconds of takeoff.
