A friend tells you she is having trouble sleeping and feels really stressed. What lifestyle change would you suggest to reduce these problems?

1. Ask her if there's anything going on in her life that she would like to talk to you about.

2. Make sure she drinks lots of water and eats the right amount of food. Not treating your body right will mostly make you feel stressed.

3. Make sure she's staying active. Staying indoors, watching TV 24/7 with the doors closed, and over-eating is very unhealthy. Germs can also build-up and cause infections which would lead you to feel uneasy.

4. And most importantly, make sure she's not in a rocky relationship.

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.
