Answer:
17 m/s
Step-by-step explanation:
Given:
Tension = 600 N
Mass of object, M= 12 kg
Radius, r = 5.78 m
Required:
Find the speed the rod will break
Here, the motor is continuously increased. To find the speed the rod will break (speed of centripetal force), we have:
Tension = Centripetal force
Where centripetal force =

Therefore,

Make v subject of the formula:





Speed the rod will break is 17 m/s.
