Angular momentum of a glancing inelastic collision

Click For Summary
SUMMARY

The discussion focuses on calculating the center of mass (CM) and angular momentum (L) for a glancing inelastic collision involving two disks. The center of mass is determined using the formula CM = Σmr / Σm, yielding a value of 0.00630614818 m. The angular momentum is calculated using L = Σ (r x p), resulting in a value of 0.00070669849 after verifying unit conversions from centimeters to meters. These calculations are essential for understanding the dynamics of inelastic collisions in physics.

Homework Equations



CM = Σmr / Σm
L = Σ (r x p)

The Attempt at a Solution



CM = 0.118 * (0.0036 + 0.00657) / (0.0723 + 0.118)
= 0.00630614818 m (from the centre of top disk)


L = Σ (r x p)
= [0.118 * (0.0036 + 0.00657) / (0.0723 + 0.118)] * 0.0723 * 1.55
= 0.00070669849
