Compute all parts of given problem:
Problem: A taut string connects a 5-kg crate to a 12-kg crate. The coefficient of static friction between the smaller crate and the floor is 0.573; the coefficient of static friction between the larger crate and the floor is 0.443.
Part A: Find the minimum horizontal force required to start the crates in motion.
Part B: What is the tension in the rope when that force is applied.
I need help to find the minimum horizontal force required to start the crates in motion.
