The following questions were asked by visitors named Maria Ellah.

A force of 300 N is sufficient to keep a 100 kg crate moving at a constant speed across a wooden floor. What is the coefficient of sliding floor?

A force of 1000 N is applied to a 1200 kg car. If the coefficient of friction is 0.04, what is the car's acceleration?

A car whose brakes are locked skids to a stop in 200 ft from an initial velocity of 50 mi/hr. Find the coefficient of sliding friction.

A force of 250 N is just sufficient to start a 50 kg steel trunk moving across a wooden floor. Find the coefficient of static friction.

A 100 lb crate is being pushed across a wooden floor with a force of 40 lb. If mu=0.3, find the acceleration of the crate.

A net force of 150 lbs acts on a body whose weight is 96 lbs. What is its acceleration? Please indicate the formula used.

Sir, gonna have some favor. What will be the formula to use?

Sir, static and kinetic are different isn't it?

4x-2=14x-92 4x-14x=92+2 -10x=94 ---- -- -10 -10 x= -9.4

thanks sir. that's what i'm gonna ask. for horizontal ground only. Godspeed! :)

Oh, I'm sorry. It should be -92+2 making it 90. Sir drwls is right. Sorry Jo. I've made mistake on the sign.

Yeah. they can. If they have intentions to somebody, well, then they would be happy when somebody did a crime to the person they want to be hurt.
