Ответ:
v = 4 m/s.
Explanation:
Given that,
Mass of the object tied on a string, m = 150 g = 0.15 kg
The radius of the vertical circle, r = 30 cm = 0.3 m
At the lowest position, the tension in the string is 9.5N.
We need to find the velocity of the mass.
At the lowest point, the net centripetal force is given by :
Putting all the values to find v.
So, the velocity of the mass is 4 m/s.
