**I have posted a word document below with various problem types from this unit so far (up to conservation of momentum). The solutions are posted on the pdf file (physicsmomentumassn.pdf)**

**I have posted an old unit 3 test if any student wants to get ahead start on the test preparation. The test will be the week of May 13 (planning for Tuesday bor Wednesday)**

**Monday** - Conservation of Momentum

- 1 board example

- impulse

- Red p 193 (2,3,4,5,8,9 &11)

- Green p 200 (30,31,33,& 34)

p 209 (37,38,39,42,43 & 45)

p 213 (46)

***** physicsimpulsemomentummay6.pdf file below ****

**Tuesday** - impulse j = FΔt

- impulse - momentum theorem FΔt = m(v_{2} - v_{1})

**Wednesday** - **Quiz # 4** (conservation of momentum & impulse-momentum theorem) ow on Friday.

**Thursday - Springs **

** - Hooke's Law F = kx**

** - Elastic potentil energy of a spring E**_{E} = 1/2 kx^{2}

** - Green text p 261(38 - 40)**

** - Sprins & conservation of energy.**

**Friday - Quiz - momentum & impulse - momentum theorem.**

** -Green text p 277 (32 & 34)**

** p 329 (24 & 25)**

** p 333 (47, 49)**
