Answer to Question #257149 in Physics for Banjjycruise

Question

A body with applied force of 5kiloNewton moves on

• A stoner ground
• On a tarred ground.

Fond which among the two floor could possess a higher coefficient of friction? And explain why?

Answer 1

The tarred ground will produce a higher coefficient of friction because tar is very sticky, which implies a stronger interaction between the molecules of the ground and body at the surface of contact.
