1 Physics 11 Mr. Jean May 3rd, 2012

2 The plan: Video clip of the day Pendulum
Conservation of energy question Science Fair etc…

3 Pendulum Motion:

4 Conservation of Energy:
m x x=0 Etotal = 1/2 mv2 + 1/2 kx2 = constant KE PE

5 Conservation of Energy with springs:
Example #1: A shopping cart with a student sitting in it has a mass of 80kg. It travels along a flat level low-friction surface (assume none!) and collides head on with a spring. The spring has a spring constant of 15500N/m. If the spring is compressed by 6 meters how fast was the cart travelling?
