Part A Learning Goal: The quantity represented by z is a function that changes over time (i.e., is not constant) To understand the meaning of the variables that appear in the equations for one-dimensional kinematics with constant acceleration. O true Motion with a constant nonzero acceleration is O false not uncommon in the world around us. Falling (or thrown) objects and cars starting and stopping approximate this type of motion. It is also the type of motion most frequently involved Submit Request Answer in introductory kinematics problems. The kinematic equations for such motion can be written as Part B I (t) = it vit+ - at?, The quantity represented by I; is a function of time (i.e , is not constant) v(t) = vi + at, where the symbols are defined as follows: O true . I (t) is the position of the particle O false at time t; . I) is the initial position of the particle; Submit Request Answer . u (t) is the velocity of the particle at time t, . v: is the initial velocity of the
