**P:**10.12, 10.22 - AQ1: In lab this week we derived a formula for the range,
*R*, for the projectile fired from the horizontally aimed gun based on five measured quantities, each with an experimental uncertainty:*m*,_{1}± δm_{1}*m*,_{2}± δm_{2}*y*_{i}± δy_{i}*y*_{1}± δy_{1}*y*._{2}± δy_{2}

The formula we found was*R = [(m*._{1}+ m_{2})/m_{1}] [4 y_{i}(y_{2}- y_{1})]^{1/2}

Use the method of partial derivatives to find the relative uncertainty*R/δR*.

- Extra Credit: Today in class we talked about a method for finding the maximum value of a function. Take a look at the kinematic equation
*y*(here I've set the initial time equal to zero and just written_{f}= y_{i}+ v_{iy}t - (1/2) g t^{2}*Δt*as simply*t*). Use the method to find an expression for the time,*t,*at which the maximum value of*y*occurs. Explain how this results jibes well with one of the other kinematic equations._{f}

What is the cost per gallon in USD? Use the web to get any additional info you need! www.x-rates.com is a good place for currency exchange rates. [CDN$ is Canadian dollars; USD$ is U.S. dollars)]- AQ 2: U.S. “proved” oil reserves are estimated to be about 32.3 billion bbl (bbl = barrels). How long will these reserves last at our current consumption rate of about 35.9 QBtu/year (2016)?
