**Physics Problem and Solution: Friction and Force Calculations**---**Problem 1: Moving a Crate**A delivery company has unloaded a 35 kg crate in your driveway. The coefficient of static friction (\(\mu_s\)) between the crate and the driveway surface is 0.70. The coefficient of kinetic friction (\(\mu_k\)) is 0.60. In order to move the crate, you apply a horizontal force of magnitude \( F \) by pushing on it. As a result, the crate slides with an acceleration of \( 5.0 \, \text{m/s}^2 \). What is the force \( F \)?**Solution:**- **Answer:** \( F = 380 \, \text{N} \)To find the force, consider the mass of the crate, coefficients of friction, and the given acceleration.Submit your previous answers if you have attempted this question before.---**Problem 2: Fridge Placement Dispute**John and Dave are having a disagreement about where to place a new refrigerator in their kitchen. As shown in Figure 1, John is applying a force \( F_J = 230 \, \text{N} \) to the right, and Dave is pushing back in the opposite direction with a force \( F_D \). The fridge has a mass \( m = 80 \, \text{kg} \). The coefficient of static friction (\(\mu_s\)) between the fridge and the floor is 0.40, and the kinetic coefficient (\(\mu_k\)) is 0.20. If Dave is pushing harder than John, what is the direction of the friction force?- **Options:** - Down - Up - From John to Dave - From Dave to JohnIn this setup, the friction force direction will oppose the net applied force to maintain equilibrium or oppose motion. ### Problem Statement:**Figure Analysis:**The diagram shows two individuals, John and Dave, on opposite sides of a refrigerator. John is on the left, pushing the fridge to the right. Dave is on the right, preparing to push the fridge to the left. The fridge is represented by a rectangular block between them.**Question:**How hard would Dave have to push in order to get the fridge moving to the left (initial moment)? Assume that John continues to apply a 230 N force to the right.**Instructions:**- Express your answer with the appropriate units.**Input Box:**- \( F_D = \) [Value] [Units]**Buttons and Options:**- Calculation-related icons are present.- A "Submit" button is available for submitting an answer.- Option to "Request Answer" for assistance.Ensure that the force applied by Dave is calculated considering the force exerted by John, using principles of physics regarding motion and equilibrium.
