Answer:

7 minutes / 7 minutos

No hablo español pero....

el solucion es

Explanation:

por explanacion :

tiempo, t = ?

distancia, d =89.66km

velocidad, v =756.66 km/h

v = d/t

vt = d

t = d/v

t = 89.66/756.66

= 0.12 hours/horas

tiempo en minutos = 0.12 × 60

= 7 minutos / minutes

Espero que yo tu ayuda.

A stone is thrown vertically upward with a speed of 18.0 m/s. How fast is it moving when it reaches a height of 11.0m? How long
steposvetlana [31]
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

Neutron stars are extremely dense objects formed from the remnants of supernova explosions. Many rotate very rapidly. Suppose th
mihalych1998 [28]

Answer:

10989.55932 rad/s

Explanation:

m = Mass of object

M = Mass of neutron star = 2\times 1.989\times 10^{30}\ kg

R = Radius of neutron star = 13000 m

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

\omega = Angular speed

Here, the gravitational force will balance the centripetal force

\dfrac{GmM}{R^2}=mR\omega^2\\\Rightarrow \omega=\sqrt{\dfrac{GM}{R^3}}\\\Rightarrow \omega=\sqrt{\dfrac{6.67\times 10^{-11}\times 2\times 1.989\times 10^{30}}{13000^3}}\\\Rightarrow \omega=10989.55932\ rad/s

The greatest possible angular speed an object can have is 10989.55932 rad/s
