A plane passes over point A with a velocity of 8000 m/s north. Forty seconds later it passes over point B at a velocity of 10000m/s north. What is the plane's acceleration from A to B?

To find the plane's acceleration from point A to point B, we can use the formula for acceleration:

Acceleration = (final velocity - initial velocity) / time

Given:
Initial velocity (v1) = 8000 m/s north
Final velocity (v2) = 10000 m/s north
Time (t) = 40 seconds

Using the formula for acceleration, we can substitute the values:

Acceleration = (v2 - v1) / t
Acceleration = (10000 m/s - 8000 m/s) / 40 s

Simplifying the equation:

Acceleration = 2000 m/s / 40 s
Acceleration = 50 m/s²

Therefore, the plane's acceleration from point A to point B is 50 m/s².

To determine the plane's acceleration from point A to point B, we can use the formula for acceleration:

acceleration (a) = (final velocity - initial velocity) / time

First, let's determine the initial velocity at point A. We are given that the plane's velocity at point A is 8000 m/s north.

Next, we need to find the final velocity at point B. We are given that 40 seconds later, the plane's velocity at point B is 10000 m/s north.

Using these values, we can calculate the acceleration:

acceleration (a) = (10000 m/s - 8000 m/s) / 40 s

Simplifying this:

acceleration (a) = 2000 m/s / 40 s

acceleration (a) = 50 m/s²

Therefore, the plane's acceleration from point A to point B is 50 m/s².
