Question

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

Answer 1

Answer:

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

Answer 2

Answer:

371 N
