Question

30. A box with mass 20kg is on a cement floor. The coefficient of static friction between the box and floor is 0.25. A man is pushing the box with a horizontal force of 35N. What is the magnitude of the force of static friction between the box and floor

Answer 1

Answer:

84.05

Explanation:

• F=mg×0.25
• F=20x9.81×0.25
• f=49.05N
• F=35N

F=f+F

F=49.05+35

=84.05
