(WILL GIVE BRAINLIEST IF YOU SHOW WORK) The force of friction between an object and the surface upon which it is sliding is 14N and the coefficient of friction between them is 0.72. What is the weight of the object?

f = 0.72 n

where f = magnitude of the friction force and n = mag. of the normal force. So we have

n = (14 N) / 0.72 ≈ 19.4 N

By Newton's second law, the object's weight and the normal force cancel, so that

n - m g = 0

where m = mass of the object and g = 9.8 m/s². Then the weight of the object is

m g = n ≈ 19 N
