Two children sitting on a sled at rest in the snow ask you to pull them. You oblige by pulling on the sled's rope, which makes an angle of 40° with the horizontal (Figure 5- 7). The children have a combined mass of 36 kg and the sled has a mass of 4 kg. The coefficients of static and kinetic friction are Ms = 0.32 and μ = 0.05. Calculate the acceleration of the children and sled, starting from rest, if the tension in the rope is 229 N. ((Your result must contain 2 digits after the decimal and must be in units of m/s2.Take g=9.81 m/s2. 2% of error will be tolerated in your answers.)
