Answer:
5.16 m/s
Explanation:
The tension in the string provides the centripetal force that keeps the object spinning in circular motion, therefore we can write:
where
T is the tension
m is the mass of the object
v is the speed
r is the radius of the circle
Here we have:
m = 280 g = 0.280 kg
r = L = 0.97 m (the radius of the circle is the length of the string)
The maximum tension allowed is
T = 7.7 N
Therefore, by solving for v, we find the maximum speed allowed before the string breaks:
