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:
Angular frequency will increase
No change in the amplitude
Explanation:
At extreme end of the SHM the energy of the SHM is given by
here we know that
now at the extreme end when one of the mass is removed from it
then in that case the angular frequency will change
So angular frequency will increase
but the position of extreme end will not change as it is given here that the top block is removed without disturbing the lower block
so here no change in the amplitude
