PrBL 1: Free Fall
The question that I chose to answer was How does introducing an initial velocity affect an object in free-fall? Be sure to discuss how d, v, and a are all affected or not affected as time passes. I chose to answer this question because I understood how to explain this one better than the other questions.
The initial velocity that the bag was being thrown at was 14. Having an initial velocity affects the VI vs. T graph because instead of starting at 0 meters it starts at 14 meters. At 0 seconds it is going at 14 meters. At one second it goes 24 meters because of the initial velocity.
The D vs. T graph gets affected by having an initial velocity because it goes further every second. With the initial velocity it goes 24 meters at one second. With out an initial velocity then it would go 10 meters in one second. Every second it goes 10 meters.
In the A vs. T graph the acceleration does not get affected because gravity is always the same even if there is an initial velocity the gravity does not change. The acceleration is 10 meters per second. The acceleration is constant. The acceleration is 10 meters per second with and without the initial velocity.

Circuit Project
For this project we had to create a circuit. For our circuit we made a parallel circuit. In our circuit we used 3 switches, a total of 7 LED lights, a motor, a dimer, a resistor and we also used a dc power. The dc power was 17 volts. The positive side of the dc power was connected to 4 LED lights then they connected to a switch(switch 2) and to 2 other LED lights. The 2 LED lights then connected back to another switch (switch 1). The negative side of the dc power was connected to a switch (switch 2) then it connected with another switch (switch 3). Switch 3 then conneted to three LED lights, a resistor and then connected back to the positive end on the dc power. The positive end of the dc power also connected to a dimmer and a moter and then back to the negative side of the dc power.
To find how much voltage each of the light bulbs needed we divided 15v by the 6 light bulbs in on series of the circuit. We got that each ligh bulb needed 2.5 volts. Then to get the other series to work we added a resistor because their was less light bulbs in that circuit.

Who's fault was it?
For this project we had to investigate who cause the collision. We had to use the information that office Bond had and use math equations to figure out who is telling the truth. I found out that Kenny was lying and he was the one that caused the accident because he was speeding. https://docs.google.com/a/snths.org/document/d/1fbJPB6Zh1dhTD7sdYGl8KNv1oK4uijC819e4v_E9FfA/edit
