Question

A coin of mass 3 g slides horizontally on the surface of a table. The frictional force exerted on the penny is 0.0147 N. What is the coefficient of friction between the table and the penny?

Answer 1

0.0147=Fn(µk)= (3kg)(9.8m/s^2)µk,

Solve for µk

Answer 2

0.0147 = 0.003*g*(µk)

µk = 0.50

Devron forgot to convert mass to kg.

Answer 3

Read it wrong. Thought mass was already given in Kg
