If a man walks 3 miles east from his house and then turns around and walks 3 miles west back to his house, what is his displacement? (answer in units of miles)

The answer is 0.

Explanation:

1. Displacement = (final position) - (initial position)

2. Displacemnet =  ("man walks 3 miles east from his house") - ("walks 3 miles west back to his house")

3. plug the numbers into places

4.  D = 3 - 3

5. D = 0

Therefore, we can conclude that his displacement is 0.

Hope I helped!! Please mark me brainliest :)

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
