1. Find angular speed of door after
collision
2. What is the change in kinetic friction?
A 1.5m wide door (mass 15kg) is hinged at one side so that it can rotate without friction about a vertical axis. It is unlatched. A police officer fires a bullet with a mass of 10g and a speed of 400m/s into the exact center of the door, in a direction perpendicular to the plane of the door. Find the angular speed of the...

4. The amount of time T (in hours) that a certain electrical component takes to fail has an exponential distribution with parameter > 0. The component is found to be working at midnight on a certain day. Let N be the number of full days after this time before the component fails (so if the component fails before midnight the next day, N = 0). (a) What is the probability that the component lasts at least 24 hours? (b) Find...
