Answer:
, 
Explanation:
The acceleration of the plane can be determined by means of the kinematic equation that correspond to a Uniformly Accelerated Rectilinear Motion.
(1)
Where
is the final velocity,
is the initial velocity,
is the acceleration and
is the distance traveled.
Equation (1) can be rewritten in terms of ax:
(2)
Since the plane starts from rest, its initial velocity will be zero (
):
Replacing the values given in equation 2, it is gotten:




So, The acceleration of the plane is
Now that the acceleration is known, the next equation can be used to find out the time:
(3)
Rewritten equation (3) in terms of t:



<u>Hence, the plane takes 26.92 seconds to reach its take-off speed.</u>
There are no true statements on the list you attached.
Answer:
Earth's average surface gravity is about 9.8 meters per second per second. ... The Moon's surface gravity is weaker because it is far less massive than Earth. A body's surface gravity is proportional to its mass but inversely proportional to the square of its radius.
Explanation:
I think it would me 5/0.5 = 10mph
Answer:
1 mile
Explanation:
We can use the following equation of motion to solve for this problem:

where v m/s is the final take-off velocity of the airplane,
initial velocity of the can when it starts from rest, a is the acceleration of the airplanes, which are the same, and
is the distance traveled before takeoff, which is minimum runway length:


From here we can calculate the distance ratio


Since the 2nd airplane has the same acceleration but twice the velocity


So the minimum runway length is 1 mile
