Question

If the friction on a table is .33, and the friction force acting on it is 20 N, what is the mass of the table?"​

Answer 1

Answer:

6 kg

Explanation:

Frictional force = 20 N

Coefficient of friction = 0.33

Frictional Force = coefficient of friction × Normal force

20=0.33 (N)

N= 20/0.33=60 kg

N= Mg

m=N/g =60/10=6 kg
