ConSlder a particle with initial velocy E that has magnitude 12.0 Ill/s and is directed 60.0 degrees above the negative X axis. Learning Goal: Projectile motion may seem rather complex at rst. However, by breaking it down into components: you , Part A will nd that it is really little dierent from the one dlmensional motions that you may already have studied. 7 _, _ What IS the x component oz of a? One of the most oftenused techniques in phy5ics is to divide two and threeedlmensional quantities into components. For instance. in projectile motion, a particle has some initial veIOClty '3. In general this velocity can point in any direction in the xy plane and can have any magnitude To make a problem more manageable. it is common to break up such a h 0 C) ? quantity into its x component '3: and its y component {3y Express your answer in meters per second. b View Available Hintis) ' PartB What is the y component y at 5?
