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 1800 m long. assume that the plane reaches the required takeoff velocity at the end of the runway. what is the time t to needed to take off? express your answer in seconds using three significant figures.

The time needed to take off is .

Explanation: Let's order the information.

From Kinematics, the law for position as a function of time is:

So the time needed to take off will fallow this rule:

⇒

⇒ ⇒

∴ .

This is the time needed to take off.

Written with only three significant figures:

.

Where the 8 stays the same since 3<5.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.  

the maxium height is 34m/s
