Answer:
Kinetic frictional force will be equal to 56.84 N
Explanation:
We have given mass of the skier m = 58 kg
Acceleration due to gravity
Coefficient of kinetic friction
We have to find the kinetic frictional force
Kinetic frictional force is given by
So kinetic frictional force will be equal to 56.84 N
Assume that the average life expectancy is about 72 years, according to recently published data.
Therefore a generation is
72/3 = 24 years.
Therefore over the last 2,000years, the number of generations that have passed is
2000/24 = 83.3
Answer: 83 generations
True b/c we conserve energy by not using energy to make new materials because we have those available because we recycled
