An airplane needs to reach a forward velocity of 56.4 m/s to take off. On a 2000 meter runway, what is the minimum uniform acceleration necessary for the plane to take flight if it starts from rest? NEED WORK SHOWN!! 100 PTs What is the displacement of the airplane?

What is the initial velocity of the airplane?

What is the final velocity of the airplane?

Write the equation you will use to solve the problem.

What was your acceleration?
1.0 m/s^2
0.95 m/s^2
0.87 m/s^2
0.80 m/s^2

Displacement of the airplane (s) = 2000 m

Initial velocity of the airplane (u) = 0 m/s (Starts from rest)

Final velocity of the airplane = 56.4 m/s

Equation used to solve the problem:

By substituting values in the equation, we get:

Minimum uniform acceleration necessary for the plane to take flight (a) = 0.80 m/s²

would be false hope this out

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
