FAYETTEVILLE STATE UNIVERSITY COLLEGE OF BASIC AND APPLIED SCIENCES DEPARTMENT OF NATURAL SCIENCES NSCI 1 1 0 12 SPRINT 2006 Review 1 and 2 PROBLEM SOLVING STRATEGY You will become skillful solving problems if you spend a great deal of time practicing this is not only important to develop problems solving skills but also will help you to understand better the material and will allow you to make your own connections and conclusions about a given topic In order words this will improve also your critique thinking skills which are essential in almost any eld of knowledge The following is a simple strategic methodology to tackle almost any problem in class I hope you will nd these notes useful 1 Analyze the Problem Read carefully and nd out what data is being given Draw diagrams if possible to Visualize the problem 2 Develop a plan to solve the problem Figure out what quantities unknowns the problem is being asked for Recognize the principles or equations that relate the data to the unknowns Develop a plan to evaluate the unknowns recognizing that your plan could involve one or series of steps 3 Solve the problem Use the equations or principles you nd out in step above to solve for the unknowns Use dimensional analysis to check the units and consistency of your solution Check also your answer for the correct number of signi cant gures 4 Check the solution Read the problem again and check that you have found out the answer to the question the problem is being asked for Is your answer outrageously small or large or is in the expected range EXAMPLE1 The speed of car changes from 15 ms to 25 ms in 20 s when the gas pedal is pressed hard Find its acceleration Apply the suggested method 1 Analyze the Problem Data V1 15 ms V2 25 ms t 20 s This data can be used to calculate the acceleration 2 Develop a plan to solve the problem This problem asks for the acceleration This quantity can be calculated using the expression a v2 v1t Calculating the acceleration from this equation we will be able to solve the problem 3 Solve the problem Calculate acceleration a v2 ivlt 25 715ms20 s 05 ms2 4 Check the solution Using dimensional analysis we nd out that the units of speed ms divided by units of time s result in units of msz these are the units of acceleration Our answer has the correct units Our answer is in the expected range of values for the change of speed of the problem EXAMPLE2 Problem 25 A woman walks 70 m to an elevator and then rises upward 40 In What is her displacement from the staring point 1 Analyze the problem In this problem making a diagram helps in visualizing the problem 40m Ori in M This data is suf cient to calculate the displacement from the initial position 2 Develop a plan to solve the problem This problem asks for the total displacement which is a vector quantity The displacement direction is evaluated using a vector departing from the tail of the rst vector to the head of the second see gure below The magnitude for the displacement can be calculated using the Pythagorean theorem Displacement A2 B2 12 40 A70mB40m In this gure the dotted vector gives the resultant displacement vector 3 Solve the problem Calculate the displacement Displacement 7 A2 132 2 7 702 402 7 6500 2 7 81 m 4 Check the solution Reading the problem again is easy to realize that the resultant displacement the vector sum of the initial displacements 40 and 70 m should be larger than that of the initial displacements of 70 and 40 m Ours result of 81 m is in agreement with this guess therefore our answer is consistently correct EXAMPLE3 Problem 221 A bicycle and rider together have a mass of 80 kg Ifthe bicycle s speed is 6 ms how much force is needed to bring it to stop in 4 s 1 Analyze the problem Data mass 80 kg vz 00 v1 6 ms t 4s v is the nal speed when the system stops This data allows calculating the acceleration of the system composed by rider and bicycle 2 Develop a plan to solve the problem The problem asks for the force required to stop the system To solve the problem rst calculate a The acceleration from the change on speed and time given using a vz 7 v1t b Calculate the force using the equation F ma 3 Solve the Problem Calculate acceleration a vz 7 v1t 00 7 60 ms4 s l5 ms2 Calculate the force F ma 80 kg l5 ms 120 N 4 Check the solution Our answer is negative this indicates that we need to apply the force in opposite direction to the displacement in order to stop the system in other words we need to de accelerate the system
