Swings on a frictionless pivot at the top end of the rod

Reference no: EM13656290

A 2.2 kg wood block hangs from the bottom of a 1.2 kg , 1.0-m-long rod. The block and rod form a pendulum that swings on a frictionless pivot at the top end of the rod. A 11g bullet is fired into the block, where it sticks, causing the pendulum to swing out to a 32 degree angle.

What was the speed of the bullet? You can treat the wood block as a particle.

Express your answer using two significant figures.
