![]() ![]() The next step of the strategy involves identifying a kinematic equation that would allow you to determine the unknown quantity. The results of the first three steps are shown in the table below. In this case, the problem requests information about the displacement of the car. (Always pay careful attention to the + and - signs for the given quantities.) The next step of the strategy involves the listing of the unknown (or desired) information in variable form. And the acceleration ( a) of the car is given as - 8.00 m/s 2. The initial velocity ( v i) of the car is +30.0 m/s since this is the velocity at the beginning of the motion (the skidding motion). Note that the v f value can be inferred to be 0 m/s since Ima's car comes to a stop. The second step involves the identification and listing of known information in variable form. The solution to this problem begins by the construction of an informative diagram of the physical situation. (Note that the direction of the velocity and the acceleration vectors are denoted by a + and a - sign.) If Ima's acceleration is -8.00 m/s 2, then determine the displacement of the car during the skidding process. The light turns yellow, and Ima applies the brakes and skids to a stop. Ima Hurryin is approaching a stoplight moving with a velocity of +30.0 m/s. The use of this problem-solving strategy in the solution of the following problem is modeled in Examples A and B below.
