The coefficient of kinetic friction between Gary's shoes and the wet kitchen

floor is 0.21. If Gary has a mass of 115 kg, what is the force of kinetic friction

acting on him as he slides across the floor?

O A. 237 N

O B. 587 N

O C. 316 N

O D. 1127 N

A. 237 N. The force of kinetic friction acting on him as he slides across the floor is Fk ≅ 237 N.

The equation of the force of kinetic friction is given by Fk = μk*N, where n = m*g. We know that the coefficient of kinetic friction between Gary's shoes and the wet kitchen floor is μk = 0.21, and Gary has a mass of 115kg. Substituting the values:

Fk = μk*n

Fk = (0.21) (115kg*9.8m/s²)

Fk = 236.67 N

Fk≅ 237 N

237 N
