Two sig figs, please. I have included table 6.1, needed for the problem. **The Skiing Duo Performance: Understanding Physics in Motion**The skiing duo of Brian (81 kg) and Ashley (54 kg) always captivates audiences with their thrilling routine. Brian, equipped with wood skis, begins his descent from the top of a 290-meter-long slope with a 20° incline. Midway down, Ashley joins him. As she skis past, she leaps into his arms, and Brian carries her for the remainder of the slope. **Question:**What is their speed at the bottom of the slope?**Instructions:**Express your answer to two significant figures and include the appropriate units.**Hint:**Use the coefficient of kinetic friction from Table 6.1 in the textbook.```plaintextv = [ ] [Units]```**Submission Tools:**- Submit Button- Request Answer Option**Note:** To solve this question, consider the principles of physics including gravitational force, friction, and momentum. **A Model of Friction**These ideas can be summarized in a model of friction:- **Static:** \( \vec{f}_s \leq (\mu_s n, \text{ direction as necessary to prevent motion}) \)- **Kinetic:** \( \vec{f}_k = (\mu_k n, \text{ direction opposite the motion}) \)- **Rolling:** \( \vec{f}_r = (\mu_r n, \text{ direction opposite the motion}) \)*(6.15)*Here, “motion” means “motion relative to the surface.” The maximum value of static friction \( f_{s \, \text{max}} = \mu_s n \) occurs at the point where the object slips and begins to move.**Note:** Equations 6.15 are a “model” of friction, not a “law” of friction. These equations—a simplification of reality—provide a reasonably accurate, but not perfect, description of how friction forces act. They are not a “law of nature” on a level with Newton’s laws.**Table 6.1 Coefficients of Friction:**| Materials | Static \( \mu_s \) | Kinetic \( \mu_k \) | Rolling \( \mu_r \) ||-------------------------|-------------------|--------------------|-------------------|| Rubber on concrete | 1.00 | 0.80 | 0.02 || Steel on steel (dry) | 0.80 | 0.60 | 0.002 || Steel on steel (lubricated) | 0.10 | 0.05 | || Wood on wood | 0.50 | 0.20 | || Wood on snow | 0.12 | 0.06 | || Ice on ice | 0.10 | 0.03 | |This table provides a list of coefficients of friction for different material combinations, illustrating how friction varies between static, kinetic, and rolling conditions.
