    What is the tension in the string at the top of the ball's path?

    Wow, I made a huge mistake... I had .6m * 9.8m/s^2 for mg... lol New MG 0.300kg * 9.8m/sec^2 = 2.94. 8 - 2.94 = 5.06 N.

    What is the tension in the string at the top of the ball's path?

    Homework Statement Picture: http://img151.imageshack.us/img151/9393/physicszn8.jpg A ball on the end of a string is cleverly revolved at a uniform rate in a vertical circle of radius 60.0 cm, as shown in Fig. 5-33. Its speed is 4.00 m/s and its mass is 0.300 kg. (a) Calculate the...

    Elevator Problem: Find Scale Reading in Falling Elevator

    Then the acceleration is equal to 0. EF = MA EF = M(0) EF = 0 Fn - Fg = 0 Fn = Fg 80(9.8) = 882 Newtons 882/9.8 = 80kg Doesn't work... Webassign says its the wrong answer... Did I do something wrong in my math?

    Elevator Problem: Find Scale Reading in Falling Elevator

    Homework Statement A 80.0 kg person stands on a scale in an elevator. (c) What does it read when the elevator is falling at 3.5 m/s? Homework Equations EF = MA The Attempt at a Solution I can't even attempt the solution because I don't know acceleration...

    Solving the Sliding Block Problem: Fig. 4-48

    Yes Devide by M on both sides and the m's cancel each other Therefore gsin(theta) = a But I already tried that.. 9.8sin(25) = 4.14

    Solving the Sliding Block Problem: Fig. 4-48

    FgTan doesn't work either... Now I am down to one last try on my webassign... Edit: It seems like it should be FgSin http://img141.imageshack.us/img141/686/fbdue2.gif

    Solving the Sliding Block Problem: Fig. 4-48

    FgTan? Because I just tried FgSin and FgCos and both didn't work.

    Solving the Sliding Block Problem: Fig. 4-48

    I'm confused how I can use Fg to find Fn, when I don't know what Fg is.

    Solving the Sliding Block Problem: Fig. 4-48

    The problem doesn't give you any mass... The problem only gives you two angles!
