    Finding voltage and current across resistors with only resistance given

    nope. that's why i can't figure out anything besides the resistance. i don't even think the question has possible answer.

    Power to Horsepower Conversion: Multiply or Divide?

    less. so IT IS divide. thanks. i knew 400,000 hp was unreasonable for a person. this was a lab btw.

    Trunk pushed up 20° incline at constant velocity with 211 N force

    oh okay. so i pretty much already found c from question b. alright. thank you.

    Trunk pushed up 20° incline at constant velocity with 211 N force

    there was no point in b. that was the dumbest question possible. I am so slow. its in equilibrium, so therefore, the sum of all the forces is 0, duh. wow. lol. yet. but i will be soon =) i don't quite understand what I am doing for question c. 211 N?

    Trunk pushed up 20° incline at constant velocity with 211 N force

    oh yeah. and is d. right? i found the coefficient the same way i found the cofficient in the other problem about the skiing. except this time, they actually gave me real numbers i could work with.

    Trunk pushed up 20° incline at constant velocity with 211 N force

    it tells you that the normal force and the Fy are equal to 325 N? then, the applied force is negative and Ff and Fx are negative? so then, Fx and the applied are equal? or Fx and Ff are equal? or Fx and Ff are equal to the applied? lol. ..no problem. i figured it was a much better set up...
