When a force of 15 newtons is applied to a stationary chair, it starts moving. What can you say about the frictional force between the chair and the floor of the room?

Question

you have to give us the statements

That the frictional force equals -15N since it is needed to equal the forces to start moving at constant speed. Do you understand that or maybe I can give you a more detailed explanation?

no thank you thats fine

anonymous · Answer

it doesn't mane the frictional force equals -15 N

it means that the MAX frictional force equals 15N.. thats the max friction that can be provided .. !!

anonymous · Answer

it means that the maximum static frictional force beween chair and floor -15 N

anonymous · Answer

ACTUALLY WE CAN JUST SAY THAT MAX VALUE OF FRICTION IS LESS THEN 15 N....
