Problem 22 (Plug-n-chug). A road runs beside and parallel to a straight stretch of railroad track. A train robber attaches his pickup truck to a boxcar, using a horizontal rope

that makes an angle of 15° to the tracks, and tows the boxcar 500 m down the tracks. If the tension in the rope was 2000 N, how much work was done on the boxcar?Give your answer in scientific notation, rounded to two significant figures. \text { (a) } 2.6 \times 10^{5} \mathrm{~J} \text { (b) } 6.5 \times 10^{5} \mathrm{~J} \text { (c) } 7.6 \times 10^{5} \mathrm{~J} \text { (d) } 9.7 \times 10^{5} \mathrm{~J} \text { (e) None of these }
