Question

Transcribed Image Text:**Scenario Description:**
In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point \( A \) on a track that is one-quarter of a circle with a radius of 1.60 m (see Figure 1). The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point \( B \) with a speed of 4.40 m/s. From point \( B \), it slides on a level surface a distance of 3.00 m to point \( C \), where it comes to rest.
**Figure Description:**
The figure shows a track with a quarter-circle arc, denoted \( A \) to \( B \), and a horizontal surface from \( B \) to \( C \). The radius of the circular arc is 1.60 m. The mass of the package is \( 0.200 \, \text{kg} \). The distance from \( B \) to \( C \) is 3.00 m.
**Part A:**
Question: What is the coefficient of kinetic friction on the horizontal surface?
Input box for entering the coefficient of kinetic friction (\( \mu_k \)).
- Note: The user is informed that they have already submitted this answer and can enter a new answer without losing credit.
**Part B:**
Question: How much work is done on the package by friction as it slides down the circular arc from \( A \) to \( B \)?
Input box for entering the work done in joules (\( W \)).
- Users are reminded to express their answer in joules.
