Answer:
ω = 10.75 rad/s
Explanation:
The stone leaves the circular path with a horizontal speed
v₀ = vt = R*ω
So
ω = v₀ / R
we are given that R = x / 25.7 so ω = 25.7*v₀ / x
Kinematics gives x = v₀*t
With this substitution for x the expression for ω becomes ω = 25.7 / t
Kinematics also gives for the vertical displacement y that
y = v₀y*t + 0.5*ay*t²
we know that v₀y = 0 m/s
since the stone is launched horizontally, so that
y = 0.5*ay*t² ⇒ t = √(2*y / ay)
Using this result for t in the expression for ω and assuming that upward is positive, we get
ω = 25.7 / √(2*y / ay)
⇒ ω = 25.7 / √(2*(-28) / (-9.8))
⇒ ω = 10.75 rad/s

Many

One of which is the falling of spaceships when they are hit by a laser beam.
Experts said, this is one good example because without gravity in space, ships
should travel in the direction of the impact instead of dropping like a stone.</span>
