Review before Test 2

Since Test 2 will take place tomorrow night, let's use class time today to solve problems illustrating the concepts which we've learned recently. Here's a brief list of some of the main topics.

• impulse and momentum
• conservation of linear momentum -- 1-D and 2-D
• center of mass
• angular kinematics
• angular dynamics -- torque and moment of inertia
• work and energy in angular motion
• angular momentum
• static equilibrium

One good source for practice problems is the

• practice Test 2
  • answers

Let's do some problems here in class.

1. Starting the engine of a plane
2. A foolish astronaut
3. A long, thin rod of variable density
4. Rope to danger
