2. A child pulls on a sled using a rope angled at 25° from the horizontal. The sled has a mass of 8 kg. Assume the snow is frictionless. What is the tension in the rope if the sled is accelerating at 0.28 m/s²? 3. The child pulls the sled up a hill. The hill is inclined at an angle of 10°. The rope is now parallel with the surface of the hill. What is the tension in the rope now, if the sled is still accelerating at the same pace? 4. Still going up the hill and pulling with a tension of 25 N, the sled encounters a rough patch with a coefficient of kinetic friction of μ = 0.1. What is the acceleration of the sled?
