Concept explainers
To Find:Aperson may escape the serious injury when hits the ground from the Parachutists.
Answer to Problem 75GP
The person will not get injured in this case.
Explanation of Solution
Given info:
Mass
Area
Initial velocity
Final velocity
Ultimate strength of the body tissue
Distance of shopping
Formula used:
Apply the 3rd equation of motion,
Here,
Write the expression for the stress.
Here,
Calculation:
Substitute the given values:
Average force per unit area would be equal to,
Conclusion:
Thus, the average force per unit area is less than the ultimate strength of the body tissue, so the person will not get injured.
