1. The problem statement, all variables and given/known data

To take off from the ground, an airplane must reach a sufficiently high speed. The velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity.

A plane accelerates from rest at a constant rate of 5.00 $$m/s^{2}$$ along a runway that is 1800m long. Assume that the plane reaches the required takeoff velocity at the end of the runway.

2. Relevant equations

What is the time needed to take off?

Hi there,

The solution to this one seems simple. You have a plane in a linear accelerated motion. Just apply the equations and the solution should pop by itself.

Cheers

Yep got it thanks!
