Determine the names of the quantities that represent input, output, and rate in the problem you are doing. In the example, Peter’s input is time , and his output is distance .
Here are my charts to measure the mover speed and what to hold for speed at distance. The mover speed chart can be used for any mover/rifle. The lead chart is rifle specific and based on time of flight.
Here are a variety of ways to calculate distances using a mil-dot reticle. The first technique is especially useful because it enables you to base your calculation on an object that is measured in inches rather than fractions of a yard. TO FIND A DISTANCE IN YARDS: An object of known size IN INCHES x 27.8
Mathematically, the BC is the Sectional Density (SD) divided by a form factor. SD is a familiar term, and is easy to calculate: SD = bullet weight/7000/caliber squared. For example, a 175 grain .308 bullet has a SD of: 175/7000/.3082 = 0.264. BC is simply the SD divided by a form factor.
1. List problems that might interfere with the accuracy of your results. 2. What problems would be encountered if we couldn’t accurately determine trajectory angle? Solve the following: 3. Angle of entry = 15° distance to building 700 feet Height of shooter ~_____ feet 4. Angle of entry = 27° distance to building 60 feet
When solving these problems, use the relationship rate (speed or velocity) times time equals distance. For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h)(4h) = 120 km.
