Inertia Physics Example 3

Solution

1. 1
   Inertia depends solely on mass. The bowling ball ($6 \text{ kg}$) has more inertia than the puck ($0.17 \text{ kg}$).
2. 2
   To stop the puck requires an impulse of $p = mv = 0.17 \times 25 = 4.25 \text{ kg m/s}$. To stop the ball requires $p = 6 \times 3 = 18 \text{ kg m/s}$.
3. 3
   The bowling ball is harder to stop because it has both greater inertia and greater momentum.
