Step 1: Identify the knowns and unknowns. Knowns: Mass (m) = 5 kg Coefficient of friction () = 0.4 Acceleration due to gravity (g) = 9.8 m/s² Unknown: Frictional force (F_f) Step 2: Calculate the normal force (N). On a horizontal surface, the normal force is equal to the gravitational force. N = m × g N = 5 \, kg × 9.8 \, m/s^2 N = 49 \, N Step 3: Calculate the frictional force (F_f). The formula for frictional force is: F_f = × N F_f = 0.4 × 49 \, N F_f = 19.6 \, N The frictional force is 19.6 N. That's 2 down. 3 left today — send the next one.
