V Part A A nonuniform horizontal bar of mass m is supported by two massless wires against gravity. The left wire makes an angle a with the horizontal, and the right wire makes an What is the position of the center of mass of the bar, measured as distance a from the bar's left end? angle B. The bar has length L. (Figure 1) Express your answer in terms of a, B, and L. View Available Hint(s) Figure 1 of 1 IVO AE ?

Part B After driving a portion of the route, the taptap is fully loaded with a total of 27 people including the driver, with an average mass of 66 kg per person. In addition, there are three 15-kg goats, five 3-kg chickens, and a total of 25 kg of bananas on their way to the market. Assume that the springs have somehow not yet compressed to their maximum amount. How much are the springs compressed? Enter the compression numerically in meters using two significant figures. What is the spring constant 1:? Express your answer with the appropriate units. A 10cmlong spring is attached to the ceiling. When a k = 400 % 2.0 kg mass is hung from it, the spring stretches to a length of 15 cm. Previous Answers V Correct Here we learn to use Hooke's law for springs supporting gravitating weights. V PartB How long is the spring when a 3.2 kg mass is suspended from it? Express your answer with the appropriate units. EHA
