Directions: On a separate sheet of graph paper, make a line graph or a bar graph that shows the decay of element Zover a 10-week period. Use your answers to questions 1-10 as your data.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
