A parent pulls a toboggan, which their child is sitting on, and which is initially at rest, up a snow-covered slope that makes a constant angle of 25 with the horizontal, as shown in the diagram. The magnitude of the parent's pulling force is 6.14m newtons, where m is the total mass of the toboggan and child in kilograms. The force is in a direction parallel to and up the slope. The coefficient of sliding friction between the toboggan and the slope is 0.22. Model the toboggan and child as a single particle and take the magnitude of the acceleration due to gravity to be g = 9.8ms^2. Give numerical answers to two significant figures
