Answer:[tex]1.68\times 10^3 N[/tex]
Explanation:
Given
mass of baseball [tex]m=0.15 kg[/tex]
Initial Speed of baseball [tex]v_1=40 m/s[/tex]
Final Speed of baseball [tex]v_2=50 m/s[/tex] (In opposite direction)
Duration of contact [tex]d t=8\times 10^{-3} s[/tex]
We know Change in momentum is equal to Impulse
Initial Momentum [tex]P_i=mv_1[/tex]
Final Momentum [tex]P_f=mv_2[/tex]
Change in momentum [tex]\Delta P=m(v_1-v_2)[/tex]
[tex]F dt=\delta P[/tex]
[tex]F \cdot 8\times 10=0.15(40-(-50))[/tex]
[tex]F=\frac{13.5}{8\times 10^{-3}}[/tex]
[tex]F=1.68\times 10^3 N[/tex]
None of the above answer matches
