2. Each diagram below shows the velocity and acceleration vectors for an object at a certain instant in time. Acceleration Velocity Instant / i. Instant 2 Instant 3 Instant 4 a. For each instant, state whether the object is speeding up, slowing down, or moving with constant speed. Explain your reasoning in each case. b. The diagram at right illustrates how the acceleration at instant 2 can be treated as having two components-one parallel to the velocity and one perpendicular to the velocity. a parallel aperpendicular i. For each of the other cases (instants 1, 3, and 4), draw a diagram similar to the one given for instant 2. Label the parallel and perpendicular components of the acceleration relative to the velocity. If either component is zero, state so explicitly. c. For each of the instants 1-4, compare your descriptions of the motion in part a with the components of the acceleration that you drew in part b. Then answer the following: Give a general rule for how the component of the acceleration parallel to the velocity affects the motion of an object. ii. Give a general rule for how the component of the acceleration perpendicular to the velocity affects the motion of an object. 2.
