On the international space station an object with mass m = 250 g is attached to a massless string l = 0.87 m. the string can handle a tension of t = 8.7 n before breaking. the object undergoes uniform circular motion, being spun around by the string horizontally. what is the maximum speed v the mass can have before the string breaks? give your answer in units of m/s.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
