Answer:
look it up im not a sheaperd sorry
Explanation:
Given: v0= 18.0 m/s, y0=0m, yf=11m, g=-9.81 m/s^2
v0= initial velocity, vf= final velocity, y0= initial height, yf= final height, g= gravity, sqrt()= square root, ^2=squared
vf^2=v0^2 + (2)(g)(yf-y0)
vf^2=(18.0 m/s)^2+(2)(-9.81 m/s^2)(11 m-0m)
vf^2=18.0 m/s)^2 + (-19.62 m/s^2)(11 m)
vf^2=(324 m^2/s^2) - (215.82 m^2/s^2)
vf^2=108.18 m^2/s^2
vf=sqrt(108.18 m^2/s^2)
vf=10.4 m/s
Answer:
10989.55932 rad/s
Explanation:
m = Mass of object
M = Mass of neutron star = 
R = Radius of neutron star = 13000 m
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Angular speed
Here, the gravitational force will balance the centripetal force

The greatest possible angular speed an object can have is 10989.55932 rad/s
It’s an Atom so this is the answer
