You may want to review pages 141-145 of your textbook for additional information.#### Question:How big is the friction force on the truck? The coefficient of static friction between the tires and the road is \(0.90\).**Express your answer to two significant figures and include the appropriate units.**#### Answer Input:The student has entered an answer:\[ f = 3400 \, \text{N} \]#### Feedback:The student's response is marked incorrect with the following notice:\[ \text{Incorrect; Try Again; 2 attempts remaining} \]---### Explanation:To solve for the friction force (\( f \)) on the truck:1. **Understand the forces involved:** - The force of gravity (\( F_g \)) pulling the truck down the slope. - The normal force (\( F_n \)) perpendicular to the slope. - The friction force (\( f \)) preventing the truck from sliding down.2. **Calculate the gravitational component acting down the slope:** - \( F_{\text{parallel}} = m \cdot g \cdot \sin(\theta) \) Where: - \( m \) is the mass of the truck (\( 4000 \, \text{kg} \)) - \( g \) is the acceleration due to gravity (\( 9.81 \, \text{m/s}^2 \)) - \( \theta \) is the slope angle (\( 20\degree \))3. **Calculate the normal force:** - \( F_n = m \cdot g \cdot \cos(\theta) \)4. **Static Friction Force:** - The maximum static friction force can be calculated by: - \( f_{\text{max}} = \mu_s \cdot F_n \) Where \( \mu_s \) is the coefficient of static friction (\( 0.90 \)).By solving these steps in sequence, the exact friction force can be determined.Do not forget to include units and ensure your final answer is expressed to two significant figures as requested. ### Problem Context:A 4000 kg truck is parked on a 19° slope.You may want to review [Pages 141 - 145].### Problem Statement:#### Part AHow big is the friction force on the truck?
