Question

A 11.0 g bullet strikes a 9.90 kg, 1.00 m wide door at the edge opposite the hinge. The bullet embeds itself in the door, causing the door to swing open with angular velocity of 2.00 rad.s-1. What was the speed of the bullet just before impacting the door? m.s-1 (3 sf)

Step 1

\[ I = \frac{1}{3}M_{\text{door}}L^2 + m_{\text{bullet}}d^2 \] \[ I = \frac{1}{3}(9.90)(1.00)^2 + (0.011)(1.00)^2 \] \[ I = 3.30 + 0.011 = 3.311 \, \text{kg m}^2 \] ** Show more…
