Homework Statement
A newly discovered asteroid orbits at twice the Earth-Sun distance. Find its period of orbit (in years).
Homework Equations
I know that I'm supposed to use Kepler's third law to determine this.
T2 = Kr3
K = 4∏2/GM
and the Earth-Sun distance is of course 1 Au...
What is the value ω stand for? I don't think I'm familiar with that equation.
Because the radius is the only thing that changes in the equation, this is what I'm thinking:
Fc = mv2/r
and
Fc = mv2/2r
2Fc = mv2/r
Therefore the longer the string the larger the centripetal force/tension. Am...
Homework Statement
Two masses M of the same amount are tied to two stings of length L and 2L. If both masses are swung in unison faster and faster, which string will break first?
Homework Equations
The formula I've been using is Tension = mv^2/r.
