SITUATION: A mother and her child are skiing together, and the mother is holding the end of a rope tied to the child's waist. They are moving at a speed of 7.2 kph on a gently sloping portion of the ski slope when the mother observes that they are approaching a steep descent. She pulls on the rope with an average force of 15 N. Knowing the coefficient of friction between the mother and the ground is 0.2, the mass of the mother is 62 kg, and the angle of the rope does not change, determine:
The acceleration of the mother
1.328 m/s^2
0.886 m/s^2
-0.886 m/s^2
-1.328 m/s^2
