Answer:
Explanation:
Given
time of contact between bat and ball is [tex]t=0.00129 s[/tex]
suppose u is the incoming velocity and v is the final velocity after collision
[tex]m=mass\ of\ ball[/tex]
Impulse exerted is given by change in momentum of the particle.
Initial momentum [tex]P_i=m\times u[/tex]
Final momentum [tex]P_f=m\times v[/tex]
Change in momentum [tex]\Delta P=P_i-P_f[/tex]
Impulse [tex]J=F_{avg}\cdot t=\Delta P[/tex]
[tex]J=F_{avg}\cdot t=m(u-v)[/tex]
[tex]F_{avg}=\frac{m(v-u)}{t}[/tex]
[tex]F_{avg}=775.2\times m(v-u)\ N[/tex]
