This question involves the concepts of tension, weight, and centripetal force.
The maximum speed, the mass can have before the string breaks is "10.26 m/s".
First, we will find the maximum tension force:
Tension = Weight
T = W = mg = (32.4 kg)(9.81 m/s²)
T = 317.84 N
Now, this tension force must be equal to the centripetal force:
where,
v = maximum speed = ?
r = radius = 1.21 m
m = mass = 3.65 kg
Therefore,
<u>v = 10.26 m/s</u>
