To find the magnitude of the frictional force acting on the crate, we can follow these steps: ### Step 1: Identify the given values - Force applied (F) = 220 N - Mass of the crate (m) = 55 kg - Coefficient of kinetic friction (μk) = 0.35 - Acceleration due to gravity (g) = 9.8 m/s² (standard value) ...
