Question

Q1. A 60-g bullet is fired horizontally with a velocity v = 300 m/s into the slender bar of a 1.5-kg pendulum initially at rest. If the bullet embeds itself in the bar, compute the resulting angular velocity of the pendulum immediately after the impact. Treat the sphere as a particle and neglect the mass of the rod. Why is the linear momentum of the system not conserved?

Step 1

First, we need to understand that the bullet and the pendulum bar form a system. Before the bullet hits the bar, the system's total angular momentum is zero because the bar is at rest and the bullet is moving in a straight line (which means it has no angular Show more…
