At high altitudes, the air pressure is lower and it is more difficult for us to breathe because we cannot take in enough oxygen.
Answer:
7.6*10^4J
Explanation:
Given that m=95kg
Final velocity= 40m/s
Using W=0.5 m (square of (final velocity) - square of (initial velocity))
= 0.5 * 95 * Squared of (40)
= 7.6*10^4J
The first law of thermodynamics states that energy cannot be created or destroyed, but it can change from one form to another

The answer to this question would be: 1m/s
When you are walking to the north with 2m/s velocity, the stationary object(velocity=0m/s) will look like moving south at 2m/s velocity. That happens because the relative distance between you and the object is reduced by 2m/s in both conditions. In this question, the man seems like have 3m/s velocity. The real velocity should be:
3m/s - 2m/s = 1m/s
