Our class entered the classroom to start off a long week early Monday morning. Like usual I walked in a tad late but was ready to go. The class started with the normal Cory being a pain and Mr. Manning allowing us to upload our power point presentations that we work on in groups the previous week. The projects were to be done on roller coasters. Danny and I worked on ours the previous day at his house. The work was nicely done and I even had a nice conversation with Betsy Way. After handing in our projects we were given time to work on practice problems. The practice problems that we began to work on dealt with horizontal and vertical velocities. I traveled back to the table in the back of the room to work with Danny and as usual Cory followed just to annoy me. While working on the problems my calculator ran out of batteries which was a huge disappointment. To solve for vertical problems one must use the formula distance traveled in meters equals one half the acceleration multiplied by the time it took squared. To solve for the horizontal problems you must use the formula distance traveled in meters equals the initial velocity multiplied by the time. The first problem that was completed used the vertical equation for the first part of the question and the horizontal part of the equation for the second part of the question. The second question used both formulas but then one more additional one. This equation is final velocity squared equals initial velocity squared plus the product of two times the acceleration times the distance traveled. Using all three of these equations given you will be able to solve any projectile problems that face you.


 * Vertical Velocity || DeltaX=1/2at² ||
 * Horizontal Velocit || DeltaX= vit ||
 * Final Velocity || vf²=vi²+2aDeltaX ||
