Problem 12.9 The acceleration of a particle as it moves along a straight line is given by a = (2t - 1) m/s², where t is in seconds. Suppose that s = 7 m and v = 7 m/s when t = 0. Part A Determine the particle's velocity when t = 6 s. Express your answer to three significant figures and include the appropriate units. v = 32 m/s Part B Determine the particle's position when t = 6 s. Express your answer to three significant figures and include the appropriate units. s = Value Units Part C Determine the total distance the particle travels during the 6 s time period. Express your answer to three significant figures and include the appropriate units. d = Value Units

Assignments 1. For the first assignment, consider the grid to be ideal, so $Z_{grid} = 0$. We use an electric furnace, which consists of 3 identical cooking plates with an impedance of R + jX. For proper operation each cooking plate should be connected to a 231V supply. a. How can you connect the furnace to each of the three given power supplies (1x231V, 3x231V and 3x400V)? Draw the circuit diagrams for each situation and indicate the line voltages and phase voltages, line currents and phase currents in these schemes. $R = 25$ $X = 12,5$ Single phase 1x231V@50Hz LO NO Threephase 3x231V@50Hz L10 L20 L30 Threephase 3x400V@50Hz L10 L20 L30 b. Measure for each circuit the values for the line voltage and phase voltage, line current and phase current and represent them in a table. c. Using the results of question b, what is (are) the current(s) that is (are) delivered by the power source, for each supply system. Compare the three systems. Explain the causes of the observed differences. What is the technical and/or economical advantage of the preferred system? d. For the three systems, measure the active power in each cooking plate. Using these results, how long will it take to boil 1l of water, from 25°C?
