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.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
