The Concord jetliner achieves a lift-off speed of 112 m/s in 20.0 seconds, starting from rest and traveling due east. What is the magnitude and direction of the average acceleration?

5.6 m/s

Explanation:

The acceleration of any possible is the ratio of the velocity of the particle with respect to the time the particle takes in moving. It is mathematically represented as

a = v/t, with m/s² as it's unit, where

v = velocity in m/s

t = time taken in seconds

a = acceleration in m/s²

From the explanation above, we were given in the question that, the speed is 112 m/s and the time if took is 20 seconds, thus, the acceleration is

a = 112/20

a = 5.6 m/s²

Therefore, the magnitude of the acceleration is 5.6 m/s²

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
