Answer:
I think it is Cinder Cone volcano.
Answer:
The axle is fixed to a frame or a block. The pulley is normally fixed to a support above the load. The load is tied to one end of the rope and the effort is applied at the other end. Such a pulley makes our work easier by simply changing the direction of the force, i.e. a load is lifted up using a downward effort.

Given:
I₁ = 0.70 kg-m², the moment of inertia with arms and legs in
I₂ = 3.5 kg-m², the moment of inertia with arms and a leg out.
ω₁ = 4.8 rev/s, the angular speed with arms and legs in.
That is,
ω₁ = (4.8 rev/s)*(2π rad/rev) = 30.159 rad/s
Let ω₂ = the angular speed with arms and a leg out.
Because momentum is conserved, therefore
I₂ω₂ = I₁ω₁
ω₂ = (I₁/I₂)ω₁
= (0.7/3.5)*(30.159)
= 6.032 rad/s
ω₂ = (6.032 rad/s)*(1/(2π) rev/rad) = 0.96 rev/s
Answer: 0.96 rev/s

Explanation:
This problem is related to parabolic motion and can be solved by the following equations:
(1)
(2)
(3)
Where:
is the horizontal distance traveled by the golf ball
is the golf ball's initial velocity
is the angle (it was a horizontal shot)
is the time
is the final height of the ball
is the initial height of the ball
is the acceleration due gravity
is the final velocity of the ball
Let's begin by finding from (2):
