Here are the answers to the problems involving motion with only an initial horizontal velocityThose who came to the after school "party" generated a series of questions which led to the answers and comments found here.. Maybe they can be of help too. LNJ

WHAT YOU NEED TO KNOW FOR TUESDAY'S ICE:

ADDING VECTORS Definition of vector Difference between number, scalar and vector Drawing vectors Sketching vector additions Finding components of vectors When given components, finding length and angle of vector Putting all this information together to add vectors Recognizing that displacement (in m, km, etc), velocity (in m/s, km/h, etc), acceleration (in m/s^2), and force (in N) are all vectors

PROJECTILE MOTION Setting up charts for 2 dimensional motion including the accelerations in the horizontal and vertical directions Recognizing that v0 in the y direction is zero when motion has an initial horizontal velocity Recognizing that v0-x = v0cos(theta) and that v0-y=v0sin(theta) when an object starts off moving at an angle with the horizontal Using the Big 5 to solve problems involving projectile motion
