Q1. While on vacation you rent a moped and go cruising around a tropical island. If you take a 10.0 degree banked curve with a radius of 15.0 meters at 12.0 m/s, what is the minimum coefficient of static friction between your tires and the road to keep the tires from slipping as you negotiate the curve?

Q2. A 10.0 g bullet is fired horizontally into a 104g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 157N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 70.0cm, what was the speed of the bullet at impact with block?
