Homework Help: Spaceship taking circular turn

  1. Apr 11, 2006 #1
    I tried using equations useing different methods of solving this problem but no cigar.

    If anyone can help me just to get started that would be grand.

    Thanks

    A spaceship negotiates a circular turn of radius 3890 km at a speed of 33860 km/h.

    (a) What is the magnitude of the angular velocity?
    rad/s
    (b) What is the magnitude of the radial acceleration?
    m/s2
    (c) What is the magnitude of the tangential acceleration?
    m/s2

    First, convert given info to correct units; meters and seconds.
    Second, use your equations for curviliear motion, they are quite basic.
    Third, the answer to c should be obvious, since the problem states that the speed is not changing....

    what equation would that be, i dont know one thats called curviliear motion equation.

    i know these equations:
    angular position
    angular velcoity - i would guess to use this but theres not rad given.
    angular acceleration

    Angular velocity can also be represented as;

    [tex]\omega = \frac{v}{r}[/tex]
