    What is the speed of the skater's hands in rotational motion?

    For Future reference, the equation for this problem is V=[2(pi)r]/t t is found per second i.e. 60/120

    What is the speed of the skater's hands in rotational motion?

    I understand that, but that is not the answer...I tried it already.

    What is the speed of the skater's hands in rotational motion?

    Nope didn't get it...I tried doing the equation v=w(pi)f wrong! Gerrrrr

    What is the speed of the skater's hands in rotational motion?

    Work. From what I understand in class V[SIZE="2"]t=Angular velocity * radius from my calculations 120rpm = 2rps and d=.130m, so C= .4082m And I multiplied 2*.4082 to find the total distance in one revolution =.8164m in one sec Now I'm stuck

    What is the speed of the skater's hands in rotational motion?

    A skater holds her arms outstretched as she spins at 120rpm. What is the speed of her hands if they are 130cm apart?
