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
