SUMMARY
The static coefficient of friction (μs) and the kinetic coefficient of friction (μk) can be calculated using the forces provided in the discussion. The static coefficient of friction is determined by the equation μs = F_static / (m * g), where F_static is the force required to set the block into motion (75.0 N), m is the mass of the block (25.0 kg), and g is the acceleration due to gravity (approximately 9.81 m/s²). The kinetic coefficient of friction is calculated using μk = F_kinetic / (m * g), where F_kinetic is the force required to keep the block in motion (60.0 N). The resulting coefficients are μs = 0.30 and μk = 0.24.
