Page 2 of 2 The following diagram applies to problem 3. H m K 3. Assume the mass has a velocity of 35 m/s in downhill direction when it reaches spring. Assume there is no friction for this problem. Develop an EXCEL file that plots the distance travelled in X direction versus velocity of mass in X direction until the mass stops. (Distance X should be on horizontal axis and velocity should be on vertical axis). The following data set applies. m= 50 kg K= 100 N/meter The following 3 problems (problems 4 through 6) do not involve use of EXCEL. They should be solved by pencil and paper and a calculator and all work must be shown in detail. 4. For the condition of problem 1, calculate mass velocity in D direction after 20 meters. 5.
