Practice it Use the worked example above to help you solve this problem. Two blocks with masses m1 = 5.08 kg and m2 = 7.56 kg are attached by a string as shown in Figure (a), over a pulley with mass M = 2.02 kg. The pulley, which turns on a frictionless axle, is a hollow cylinder with radius 0.0570 m over which the string moves without slipping. The horizontal surface has coefficient of kinetic friction 0.336. Find the speed of the system when the block of mass m1 has dropped 1.94 m. m/s Exercise Hints: Getting Started I'm Stuck! Two blocks with masses m1 = 1.90 kg and m2 = 9.10 kg are attached over a pulley with mass M = 3.10 kg hanging straight down as in Atwood's machine (see Figure (b). The pulley is a solid cylinder with radius 0.0460 m, and there is some friction on the axle. The system is released from rest, and the string moves without slipping over the pulley. If the larger mass is traveling at a speed of 2.21 m/s when it has dropped 1.0 m, how much mechanical energy was lost due to friction in the pulley's axle? W. J Hint: This exercise is slightly easier than the associated example because the friction force need not be determined. Need Help? Read It

1. Gross profit: To calculate the gross profit for 20X1, we need to subtract the cost of goods sold from the net sales. Unfortunately, the cost of goods sold is not provided in the given texts, so we cannot determine the gross profit. 2. Number of days sales in average receivables: To calculate the number of days sales outstanding in average receivables for 20X1, we need to divide the net accounts receivable at December 31, 20X1 by the average daily sales. However, the average daily sales are not provided in the given texts, so we cannot determine the number of days sales outstanding in average receivables. 3. Number of days sales in average inventories: To calculate the number of days sales outstanding in average inventories for 20X1, we need to divide the inventories at December 31, 20X1 by the average daily cost of goods sold. However, the average daily cost of goods sold is not provided in the given texts, so we cannot determine the number of days sales outstanding in average inventories.

section A. Multiple choice questions: [50 marks] Indicate the correct answer in the box provided. 1. To decide whether $y_i = \beta_1 + \beta_2x_i + e_i$, or $ln y_i = \beta_1 + \beta_2x_i + e_i$ fits the data better, you cannot consult the regression $R^2$ because: a. the natural logarithm of $y_i$, $ln y_i$, may be negative for $0 < y_i < 1$. b. the TSS are not measured in the same units between the two models. c. the slope no longer indicates the effect of a unit change of $x_i$ on $y_i$ in the log- linear model. d. the regression $R^2$ can be greater than one in the second model. 2. Suppose that the variable $x_3$ has been omitted from the following regression equation: $y_i = \beta_1 + \beta_2x_{2i} + \beta_3x_{3i} + e_i$ where $\beta_2$ is the estimator obtained when $x_3$ is omitted from the equation. The bias of $\beta_2$ is positive if: a. $\beta_3 > 0$ and $x_2$ and $x_3$ are positively correlated. b. $\beta_3 < 0$ and $x_2$ and $x_3$ are positively correlated. c. $\beta_3 > 0$ and $x_2$ and $x_3$ are negatively correlated. d. $\beta_3 = 0$ and $x_2$ and $x_3$ are negatively correlated.
