Answer:
is called square of Coefficient of Restitution
Explanation:
As we know that the coefficient of restitution is the ratio of the body after collision to the ratio of the body before collision.
Mathematically:
[tex]e=\frac{v_f}{v_i}[/tex]
where:
[tex]v_f=[/tex] relative velocity after collision
[tex]v_i=[/tex] relative velocity before collision
also, in terms of Kinetic energy:
[tex]e=\sqrt{\frac{KE_f}{KE_i} }[/tex]
where:
[tex]KE_f=[/tex] relative kinetic energy after collision
[tex]KE_i=[/tex] relative kinetic energy before collision
