The baseball of mass 140g travels at a speed of 30 m/s.
Its momentum is
P₁ = (140 x 10⁻³ kg)*(30 m/s) = 4.2 (kg-m)/s
Part a.
The momentum is dissipated in 1.5 s.
The average force, F, that dissipates the momentum is
(F N)*(1.5 x 10⁻³ s) = 4.2 (kg-m)/s
F = 2800 N = 2.8 kN
Answer: 2.8 kN
Part b.
The average force that the baseball exerts on the head is 2.8 kN, as obtained in part a.
This is true if the time to dissipate the momentum is 1.5 ms.
Answer: 2.8 kN
Part c.
Answer:
(a) The forehead will not fracture because 2.8 kN < 6.0 kN.
(b) Your cheek will fracture because 2.8 kN > 1.3 kN

Personal and community wellness frequently exhibit high correlations with educational achievement and associated levels of income. It's true to say this.
Discussion
In the previous ten years, the United States median household income has grown less rapidly. The median income for all workers has increased more steadily since 2000 than it did in the 1990s, and the wages of full-time employees have a significant influence on income patterns.
Education level is one aspect that can be affecting the reduction in wages. Educated individuals are more likely to participate in the labor force, get work, and experience other favorable labor market outcomes, according to research.
When researchers evaluate incomes by educational attainment, they may observe extremely clear patterns. There have been significant disparities in median incomes over the last ten years amongst groups with varying degrees of achievement.
