** Samir Shah, Shayna Lans, Ellen Seong **
__**LOG:**__

Today, we went over the glancing collisions worksheet.
 * Monday, April 26:**

We started the crush lab.
 * Tuesday, April 27:**

We had a double-period today and three lab assignments to complete. We completed the crush energy lab today that we had began yesterday. Shayna completed those calculations**.** Samir & Ellen completed the two other labs, involving human reaction time and coefficient of kinetic friction on asphalt (it started to drizzle during the execution of the latter experiment). We intend on reading the Overview & the skimming the ELVA booklet tonight. We will begin planning our agenda for the trial tomorrow.
 * Wednesday, April 28:**

Samir was out today. Shayna calculated crash energy of the actual accident scenario. Ellen studied the roads and the scenario and measured the skid marks. The group is intending to visit the site soon just in case Mill Rd is a one-way road.
 * Thursday, April 29:**

Shayna & Ellen also reassigned responsibilities/roles. Shayna will maintain her position as Lawyer/Prosecutor. Samir will now be the Police Expert, and Ellen will now be the Expert Witness. Today, Shayna & Ellen chipped away at most of the technicalities of the scenario. Shayna is finishing the crush energy calculations this evening and will be prepared to present her findings to her fellow group members tomorrow. As Ellen worked the full period today to measure the skid marks, calculate the drag factor, etc., Samir should will do the same calculations this evening and be prepared to compare/collaborate with Ellen during tomorrow's class. We will then have a substantial amount of calculations complete, and can therefore move forward in our plan to present our defense in the trial.

Today we worked towards identifying the speed of the car prior to collision. Samir did the calculations at home, and identified some inconsistencies in Ellen's calculations. He also found some pictures of the crash scene on Google Earth. We broke up the crash into three different events, and solved for the energy lost during each event. Together, that energy is equal to the initial kinetic energy of the moving vehicle. We can ultimately calculate the velocity of the vehicle prior to slamming on its breaking and crashing into the other vehicle by using KEi = 1/2mv(i)^2.
 * Friday, April 30**:

The group intends on meeting Saturday afternoon to gather & polish our information for the trial. Once we evaluate our progress on Saturday, we may or may not meet again on Monday morning to discuss our plan of attack. :)

Shayna went to the actual scene of the collision & took pictures. These pictures evidence driver two's wrongdoings & greatly support our position. **:**)
 * Sunday, May 2nd:**

The group will meet tomorrow morning at 7:3o. For Wednesday's trial: Shayna will be the lawyer, Samir will be the Police Witness/Technical Assistant & Ellen will be the driver (MV1).

= = = = Today, Bilash explained that we do not need our driver to testify. So, we re-established the role & responsibility of each member. Samir: Samir must fully understand the details of the scene of collision, as he is the police witness and will virtually re-state/uphold what was stated in the accident report. Ellen: Ellen must fully understand the calculations/mathematical evidence. She will also create a Powerpoint Presentation -- containing image/calculation evidence -- tonight. Shayna: Shayna must ask questions of Ellen that will serve as an introduction to the defensive position. She must also prepare questions to ask the prosecution. She will prepare those questions tonight -- collaborate with her attorney daddy **:**) -- and will rehearse with her groupmates tomorrow.
 * Monday May 3rd:**
