Transcribed Image Text:**Problem Statement:**
A 200-kg snowmobile with a passenger is traveling down a hill. At point \( A \), it is moving 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 Explanation:**
The diagram shows a curving slope with an x-y coordinate system. The slope is defined by the equation \( y = -5(10^{-3})x^3 \).
- The point where the snowmobile is, labeled \( A \), is at the coordinates:
- \( x = 10 \) m
- \( y = 5 \) m
**Calculations:**
The given answers for the forces are:
- Normal force at \( A \), \( N_A = 924.8 \, \text{N} \)
- Frictional force at \( A \), \( f_A = 1232 \, \text{N} \) (directed opposite to the direction of travel for the snowmobile)
**Note:** The forces calculated are based on the dynamics of the snowmobile as it travels on the curved path.
