Q. Coefficient of restitution is defined as the ratio of

पुनर्स्थापन के गुणांक को अनुपात के रूप में परिभाषित किया गया है

A
Initial to final velocity
प्रारंभिक से अंतिम वेग
B
Final to initial momentum
आरंभिक गति के लिए अंतिम
C
Relative speed after to before collision
टक्कर के बाद से पहले तक सापेक्ष गति
D
Force to acceleration
त्वरण के लिए बल

Explanation

The coefficient of restitution (e) quantifies how "bouncy" a collision is. It is defined as:

e=Relative speed after collisionRelative speed before collision=v2′−v1′v1−v2e = \frac{\text{Relative speed after collision}}{\text{Relative speed before collision}} = \frac{v_2' - v_1'}{v_1 - v_2}

where v1,v2 are initial velocities, and v1′,v2′v_1', v_2' are final velocities of two bodies. It ranges from 0 (perfectly inelastic) to 1 (perfectly elastic).
