A diver who has a mass of 68 kg climbs to a diving platform that is 7.5 m above the surface of a pool. How much gravitational po
2 answers:
Answer: 4,998 J
Explanation:
The gravitational potential energy of an object is given by
where
m is the mass of the object
g is the gravitational acceleration
h is the heigth of the object with respect to a reference point
In this problem, m=68 kg, g=9.8 m/s^2, and h=7.5 m is the heigth of the diver with respect to the surface of the pool. Therefore, the gravitational potential energy of the diver with respect to the surface of the pool is

Answer:
The angular velocity is 15.37 rad/s
Solution:
As per the question:
Horizontal distance, x = 30.1 m
Distance of the ball from the rotation axis is its radius, R = 1.15 m
Now,
To calculate the angular velocity:
Linear velocity, v =
v =
v =
v =
Now,
The angular velocity can be calculated as:
Thus
