Determine the frictional force acting on a body that slides on a horizontal surface if the coefficient of friction is 0.15a and the body weight is 20kg.
Given:
m = 20 kg
U = 0.15
g = 10 m / s2
Find: Ftr -?
Decision:
Ftr = u N
| N | = | Ftyazh | according to Newton’s 3 law
Ftyl = mg
Ftr = u * mg = 0.15 * 20 * 10 = 30N
Answer: 30N.
