Physics

Your neighbor is pushing a 44.0-kg bag of dirty laundry across aparking lot as shown in the figure below. The coefficient of staticfriction between the bag and the asphalt is 0.1, and thecoefficient of kinetic friction is 0.03. Assume that up and rightare the positive directions.Determine the following for case (a), where he'spushing downward at an angle of 25°. (a) Calculate the minimumforce F he must exert to get the stinky bag moving. Fmin = N (b)What is its acceleration once it starts to move, if that force ismaintained? a = m/s2 PopUp: Force Equations 2. Determine thefollowing for case (b), where he's pulling upward at an angle of 25°. (a) Calculate the minimum force F he must exert to get thestinky bag moving. Fmin = N (b) What is its acceleration once itstarts to move, if that force is maintained? a = m/s2
