A ladder of length 10 m and mass 25 kg leans against a smooth wall such that it is at an angle of 57∘ to the horizontal.  A man of mass 70 kg stands at the point A marked in the diagram, a distance d from the foot of the ladder. The coefficient of friction between the ground and the ladder is 0.1. A)Find the magnitude of the normal reaction force N acting at the foot of the ladder.

B) What is the relationship between the magnitude of the friction F acting on the foot of the ladder, and the magnitude of the normal reaction R, acting at the top of the ladder. Write your answer as a mathematical equation (using the "=" sign) involving F and R

The bubba chump shrimp company processes and packages shrimp for sale to wholesale seafood distributors. the shrimp are transported to the main plant by trucks that carry 1,000 pounds (lb) of shrimp. once the continuous flow processing of the shrimp begins, no inventory is allowed in buffers due to spoilage and all of the shrimp must be processed within 12 hours to prevent spoilage. the processing begins at the sorter, where the trucks dump the shrimp onto a conveyor belt that feeds into the sorter, which can sort up to 500 lb per hour. the shrimp then proceed to the desheller, which can process shrimp at the rate of 400 lb per hour. however, after 3 hours and 45 minutes of processing, the desheller must be stopped for 15 minutes to clean out empty shrimp shells that have accumulated. the veins of the shrimp are then removed in the deveining area at a maximum rate of 360 lb per hour. the shrimp proceed to the washing area, where they are processed at 750 lb per hour. finally, the shrimp are packaged and frozen. what is the daily process capacity of the processing plant (excluding the packaging and freezing)?
