An airplane touches down on the runway at 37 m/s after 8 seconds, the airplane has slowed to a velocity of 5 m/s. what is a plane's acceleration?​

Explanation:

Acceleration is the rate at which an object changes its velocity. It is the change in velocity over the change in time.

The change in velocity is the difference between the final velocity and the initial velocity.

The airplane touches down at 37 meters per second, the slows to 5 meters per second. The final is 5 m/s and the initial is 37 m/s.

The change in time is also how much time it took for the velocity to change. In this case, the change in time is 8 seconds.

Now we know the values for the variables:

Substitute the values into the formula.

Divide.

The acceleration is -4 meters per square second. Since the acceleration is negative, the airplane is slowing down.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
