    Some guidance please Newton's Laws

    I was afraid it would seem that way if i didn't describe all my attempts to solve it. I am confused, my best bet was to use the equation F= m*a because i know that I could find my acceleration from this formula So I applied it using the numbers from the problem m=w/9.8 m=897/9.8 = 91.53...

    Some guidance please Newton's Laws

    A1000N crate is being pushed across a level floor at a constant speed by a force of 300N at an angle of 20 degrees below the horizontal. (a) what is the coefficient of kinetic friction between the crate and the floor I was able to find this which is = .26 (b) If the 300N force is instead...

    Quick question about normal force

    I agree with that... didn't mean to sell anybody short on their physics talent :^)

    Quick question about normal force

    so the weight is 216 N = 216 - 29 = 187 BY GEORGE THINK I'VE GOT IT... yeah?

    Quick question about normal force

    Warren- I typed the wrong thing... i meant 29 N for the vertical component, right? another confusion i have is, is 20 kg the weight, or mass?

    Quick question about normal force

    This may be very simple... but here is the question. This is the question.. A woman at an airport is towing her 20.0 kg suitcase at constant speed by pulling on a strap at an angle of (theta) above the horizontal. She pulls on the strap with a 35.0 N force, and the friction force on the...
