Q1. How fast (in {rm rpm}) must a centrifuge rotate if a particle 5.00 cm from the axis of rotation is to experience the acceleration of 116660 {rm g}'s?

Q2. A gun is fired vertically into a 2.00 kg block of wood at rest straight above it. If the bullet has a mass of 21.0 g and a speed of 198 m/s, how high would the block rise into the air after the bullet becomes embedded in it?
