2. Two masses, \( A=2.0 \mathrm{~kg} \) and \( B=4.0 \mathrm{~kg} \), slide along an air track without friction. Initially, \( A \) is located at \( x=0.0 \mathrm{~m} \), and has a velocity of \( 12 \mathrm{~m} / \mathrm{s} \) in the \( +x \) direction, and \( B \) is located at \( x= \) 1.0 m and is at rest. After they collide, both masses move together. A) Use conservation of linear momentum to calculate the common velocity of the two- mass system after the collision. B) How much kinetic energy was lost due to this collision?

Part 1 of 2 (a) Find the rational zeros and then the other zeros of the polynomial function \( f(x)=x^{3}-133 x+132 \); that is, solve \( f(x)=0 \). (b) Factor \( f(x) \) into linear factors. (a) Select the correct choice below and fill in any answer box(es) within your choice. (Type integers or fractions. Use a comma to separate answers as needed. Type exact answers, using radicals as needed. E A. There are only rational zeros and the zeros are \( \square \). The rational zero(s) is/are \( \square \), and the other zero(s) is/are \( \square \). C. There are no rational zeros. The other zeros are \( \square \).

punto \( A(-1,5) \) se traslada transformándose en el punto \( A^{\prime}(2,3) \). Si al punto \( B(-2,4) \) se aplica la misma traslación, quedará en el punto.

This table from the National Census shows what type of energy different households use for lighting their homes. Draw a horizontal bar graph to show what percentage of homes use electricity, paraffin or candles to light their homes. Use a scale of 1 cm to \( 10 \% \) on the horizontal axis.
