Question

The Winchester Arms company tabulates the following data on it's standard velocity

22LR ammunition. The bullet's speed is measured at the following distances (given in

yards) down range from the muzzle: {0, 25, 50, 75, 100, 125, 150, 175, 200} and, at

those distances, they obtain the following speed values in ft./sec. {1116, 1062, 1017,

979, 947, 918, 891, 866, 843}. Form a table of these distances and speeds (form extra

columns to express in SI units!) and then compute the average speed and average

acceleration over each of the distance intervals and record them in your table (assume

constant acceleration over any one interval as an approximate working model). Form

two final columns in your table to record your estimate of the time elapsed over each

interval and the total elapsed time at the end of each interval. Finally, form a graph of

average acceleration versus average speed and comment briefly on the qualities of highvelocity

ballistics (we will use this final data for further analysis in a few weeks)
