Question

Which of the following options is/are true regarding inelastic collision?

• A. Impulse of reformation is greater than impulse of deformation
• B. $0<e<1$
• C. Impulse of reformation is less than Impulse of deformation
• D. $e>1$

Answer 1

Answer: (B), (C)

Impulse of reformation is less than Impulse of deformation

We know $\text{Coefficient of restitution(e)}=\frac{\text{Impulse of reformation}}{\text{Impulse of deformation}}$
In an inelastic collision, $0<e<1$
$\therefore$ Impulse of reformation < Impulse of deformation
Option (b) and (c) are correct.
