I’m not sure maybe attach a image or something
Answer:
Tangential speed = 5.72 m/s
Centripetal acceleration = 
Explanation:
The tangential speed, V, is given by

where
is the angular speed and is given by
(f is the angular frequency or frequency of rotation)
Thus,

The centripetal acceleration,a, is given by


C. A flow of matter from one point to another.
<u>Answer:</u>
The height of the cliff in meters = 27.44
<u>Explanation:</u>
The potential energy of a body is given by the expression, PE = mgh, where m is the mass of the body, g is the acceleration due to gravity value and h is the height of the body.
Here we have mass of rock = 13 kg
Potential energy = 3500 J
Acceleration due to gravity = 
Substituting 3500 = 13 * 9.81 * h
h = 27.44 meter
The height of the cliff in meters = 27.44
