**Problem Statement:** The 200-kg snowmobile with a passenger is traveling down the hill such that when it is at point A, it is traveling at 4 m/s and increasing its speed at 2 m/s². Determine the resultant normal force and the resultant frictional force exerted on the tracks at this instant. Neglect the size of the snowmobile. **Diagram Description:** - The diagram features a slope with a snowmobile positioned on it. - The slope's curve is defined by the equation \( y = -5(10^{-3})x^3 \). - Point A, where calculations are to be made, is 10 meters along the x-axis from the origin and 5 meters down the slope. - Coordinate axes are labeled \( x \) and \( y \). **Solution:** Given: - Mass of snowmobile (including passenger) = 200 kg - Velocity at point A = 4 m/s - Acceleration at point A = 2 m/s² **Answers:** - Resultant normal force, \( N_A = 924.8 \, \text{N} \) - Resultant frictional force, \( f_A = 1232 \, \text{N} \) (Directed opposite the direction of travel for the snowmobile)
