Problem 13:
Renatta Gas did it again. She failed to fill up her tank during the last four weeks. The velocity-time graph below represents the last six seconds of motion her car before being stranded on a highway in route to her university.
Use this graph to determine …
a. … the acceleration of Renatta's car.
b. … the distance traveled during her last 6.0 seconds of motion.

Habits of an Effective Problem Solver
-
Read the problem carefully and develop a mental picture of the physical situation. If necessary, sketch a simple diagram of the physical situation to help you visualize it.
-
Identify the known and unknown quantities in an organized manner. Equate given values to the symbols used to represent the corresponding quantity - e.g., vo = 0 m/s; a = 4.2 m/s/s; vf = 22.9 m/s; d = ???.
-
Use physics formulas and conceptual reasoning to plot a strategy for solving for the unknown quantity.
-
Identify the appropriate formula(s) to use.
-
Perform substitutions and algebraic manipulations in order to solve for the unknown quantity.
