Question

a 200-gram ball is whirled around in ahorizontal circle at the end of string 1000 cm long.what is the highest speed the object can have if the string has breaking point of 4 N

Answer 1

Answer:

mass=0.2 kg , radius=10 m, T =4N

Explanation:

T = mv^2/r

4= (0.2) v^2/10

v^2 = 4×10/0.2

v^2 = 200

v = √200 =10√2 m/s^2.

Answer 2

Answer: 10√2 m/s*2

I hope it helps uh.
