Alan slides across home plate during a baseball game. if he has a mass of 61
kg, and the coefficient of kinetic friction between him and the ground is 0.62,
what is the force of friction acting on him?
o a 410n
o b, 591 n
o c. 490 n
od 371 n

D. 371 N

Explanation:

Friction force equals normal force times the coefficient of friction:

F = Nμ

Since the ground is level, normal force equals weight:

N = mg

Therefore:

F = mgμ

F = (61 kg) (9.8 m/s²) (0.62)

F = 371 N
