Fast reactions: In a study of reaction times, the time to respond to a visual stimulus (x) and the time to respond to an auditory stmords were recorded for each of 8 subjects. Times were measured in thousandths of a second. The results are presented in the following table. Visual Auditory 161 159 176 163 178 201 188 193 191 169 201 197 203 206 211 189 Send data to Excel The least-squares regression line $\hat{y}=b_0 + b_1x = 53.4243 + 0.6956x$ and $\sum (x-\bar{x})^2 = 1901.8750$ are known for this data. Construct a 95% confidence interval for the slope. Round the answers to at least four decimal places. The 95% confidence interval is $\boxed{}$ < $\beta_1$ < $\boxed{}$ .

An arrow is shot into the air and moves along the parabolic path $y = x(50 - x)$ (see figure). The horizontal component of velocity is always 10 ft/s. What is the vertical component of velocity when (i) $x = 10$ and (ii) $x = 40$? (i) Calculate the derivative of $y = x(50 - x)$ with respect to time. $\frac{dy}{dt} = \boxed{} \frac{dx}{dt}$

2. A particle moves in a central force field given by the potential $V = -k \frac{e^{-ar}}{r}$, where $k$ and $a$ are positive constants. Using the method of the equivalent one-dimensional potential discuss the nature of the motion, stating the ranges of $l$ and $E$ appropriate to each type of motion. When are circular orbits possible? Find the period of small radial oscillations about the circular motion.
