Great Suggestions for Success Mechanics Lecture 1, Slide 4

5
Questions/Suggestions Mechanics Lecture 1, Slide 5 Each component can be treated separately. Remember that they are component of a vector Kinematic equations for displacement,velocity and acceleration are the source for the derived equations. For this situation the horizontal component of the velocity remains constant. The vertical component of velocity changes due to the gravitational acceleration.
