## 1-Dimensional Kinematics: Audio Guided Solution

#### Extra Problem 2:

If the average speed of an orbiting space shuttle is 19600 miles per hour, find the time (in hours) required for it to circle the earth. Use the distance around the earth in your calculation and neglect the fact that the shuttle is about 205 miles above the earth's surface. (GIVEN: 1 m/s = 2.24 mi/h; Earth radius = 6.36 x 106 m.)

## Habits of an Effective Problem Solver

An effective problem solver by habit approaches a physics problem in a manner that reflects a collection of disciplined habits. An effective problem-solver...

• ...reads the problem carefully and develops a mental picture of the physical situation. If needed, they sketch a simple diagram of the physical situation to help visualize it.
• ...identifies the known and unknown quantities in an organized manner, often times recording them on the diagram iteself. They 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 = ???.).
• ...plots a strategy for solving for the unknown quantity; the strategy will typically center around the use of physics equations be heavily dependent upon an understaning of physics principles.
• ...identifies the appropriate formula(s) to use, often times writing them down. Where needed, they perform the needed conversion of quantities into the proper unit.
• ...performs substitutions and algebraic manipulations in order to solve for the unknown quantity.
