A car with a mass of 800 KG sitting at an intersection blows into two pieces. The piece that moves to the right has a mass of 480 KG. It moves with a speed of 15 M/S. How might you use what you know about momentum to determine the mass and velocity of the other half.

tube or goog with be a great resource to with that question

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
