A plane accelerates from rest at a constant rate of 5.00 m/s2 along a runway that is 1800 m long. Assume that the plane reaches the required takeoff velocity at the end of the runway.

Step 1

Given values:

Acceleration of the plan, a = 5.00 m /s2

Length of runway, S = 1800 m

Initial velocity of the plane, u = 0

Step 2

Let the required takeoff velocity be v

From third equation of motion:

Step 3
