**Problem Statement:**Coefficient of kinetic friction between the mass and the incline is 0.2. Find the minimum work done to slide the mass from the bottom to the top of the incline.**Diagram Explanation:**- The diagram shows a 10 kg block on an inclined plane with an angle of $ \theta = 30^\circ $.- The height of the incline is given as $ h = 4 \, \text{m} $.- A force, $ f_1 = 50 \, \text{N} $, is applied parallel to the incline.- The coefficient of kinetic friction is 0.2.**Physics Concepts:**The work done to move an object up an incline is calculated considering gravitational forces, frictional forces, and any applied force. The work done $ W $ can be expressed as:\[ W = mgh + f_f d \]where:- $ m $ is mass of the object,- $ g $ is the acceleration due to gravity $ (9.8 \, \text{m/s}^2) $,- $ h $ is the height of the incline,- $ f_f $ is the frictional force,- $ d $ is the distance along the incline.The distance $ d $ can be found using trigonometry:- $ d = \frac{h}{\sin(\theta)} $.The frictional force $ f_f $ is calculated as:\[ f_f = \mu_k \cdot N \]Where $ N $ is the normal force.The normal force $ N $ on an incline is:\[ N = mg \cos(\theta) \]Therefore, the work done against friction is:\[ W_{\text{friction}} = f_f \cdot d = \mu_k \cdot mg \cos(\theta) \cdot d \]Finally, add these components to find the total work done to overcome gravity and friction.
