Thedifference in the forces exerted by the male lions and human sprinter on the ground during a race.
Answer to Problem 62A
The differences in the forces exerted by the male lions and sprinter on the ground during the race is
Explanation of Solution
Given info:
The acceleration of both the male lions and human sprinters is
The weight of the lion is
The weight of human sprinter is
Consider the forces exerted by the male lions on the ground is denoted by
Consider the forces exerted by the human sprinter on the ground is denoted by
Formula used:
Newton’s Second Law: The object’s acceleration is equivalent to the sum of the forces acting on the object divided by the object’s mass. That is,
Calculation:
Both male lions and human sprinter exerts forces on the ground during the race.
Find the forces exerted by the male lions on the ground as follows:
Apply Newton’s Second Law:
Find the forces exerted by the human sprinters on the ground as follows:
Apply Newton’s Second Law:
Find the difference in the forces exerted by the male lions and human sprinter as follows:
Conclusion:
Thus, the differences in the forces exerted by the male lions and human sprinter on the ground during the race is
