Download Solution PDFConcept:
The energy dissipation during impact is called by the term, coefficient of restitution, a scalar quantity
\(e = \frac{{velocity\;of\;separation}}{{Velocity\;of\;approach}}\)
\(e = \frac{{{v_1} - {v_2}}}{{{u_2} - {u_1}}}\)
where, v = velocity of the body after impact, u = velocity of the body before impact
- For perfectly elastic collision, e = 1
- For inelastic collision, e < 1
- For a perfectly inelastic collision, e = 0
