An airplane originally at rest on a runway accelerates uniformly at 6.0 meters per second2 for 12 seconds. during this 12-second intervai, the airplane travels a distance of approximately

answer

22.5 m/s

explanation

we shall use the trigonometric ratio cosine to find the horizontal component.

cos = adjacent/hypotenuse

adjacent is the horizontal and hypotenuse is the fly speed.

cos 30° = horizontal / 26

horizontal velocity = 26 × cos 30°

                                = 26 × 0.866

                                = 22.5166

                                  = 22.5 m/s

1) length of the wire.

2) thickness of the wire.

3) temperature.

4) type of metal.

hope this !

explanation :

momentum of a body is defined as the product of its mass and velocity.

    i.e.

so, when an object is moving, it has momentum.

if and are the masses of objects a and b and are their initial velocities. so, their initial momentum will be:

if after collision it bounces back with same velocities, then final momentum becomes:

-ve sign shows that the motion is in opposite direction.

so,

or

hence, its final momentum is in opposite direction of initial momentum.

the formula for acceleration is the velocity times the inverse of time so it would be 21 times 1/13. so roughly 0. is the acceleration(m/s^2).
