An airplane turning from south to west at constant speed is accelerating due to a change in

Cause of acceleration:

As, each body or object having a mass,m will acquire some acceleration,a while moving in a given direction.But, the acceleration, α can also be acquired if the body is changing its direction continuously(it occurs when moving in a circle).

Explanation:

Acceleration due to change in direction:

When a body is moving from south to west while having a constant speed it will then acquire some amount of acceleration which is not due to change in velocity,v but it is all due to change in its direction.It will cause the plane to accelerate in that direction.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

pe = weightxheight = 2000x1000=2,000,000joules
