Problem: A horse is exerting a force (F=3400?NF = 3400 \, \text{N}F=3400N, of course!) on a sleigh whose mass=610?kg\text{mass} = 610 \, \text{kg}mass=610kg. The sled slides along the snowy Ruston countryside, where ?s=0.2\mu_s = 0.2?s?=0.2 and ?k=0.15\mu_k = 0.15?k?=0.15, with an acceleration closest to: Answer Choices: (A) 2.95?m/s22.95 \, \text{m/s}^22.95m/s2 (B) 3.16?m/s23.16 \, \text{m/s}^23.16m/s2 (C) 3.38?m/s23.38 \, \text{m/s}^23.38m/s2 (D) 3.61?m/s23.61 \, \text{m/s}^23.61m/s2 (E) 3.87?m/s23.87 \, \text{m/s}^23.87m/s2 (F) 4.14?m/s24.14 \, \text{m/s}^24.14m/s2 (G) 4.43?m/s24.43 \, \text{m/s}^24.43m/s2 (H) 4.74?m/s24.74 \, \text{m/s}^24.74m/s2 (I) 5.07?m/s25.07 \, \text{m/s}^25.07m/s2 (J) 5.42?m/s25.42 \, \text{m/s}^25.42m/s2
