Question
To test the speed of a bullet, you create a pendulum by attaching a 5.40 kg wooden block to the bottom of a 2.40 m long, 0.700 kg rod. The top of the rod is attached to a frictionless axle and is free to rotate about that point.
You fire a 10 g bullet into the block, where it sticks, and the pendulum swings out to an angle of 32.5°. What was the speed of the bullet?
