Answer:
The person must be located in the Equator Line. The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Explanation:
Physically speaking, the centripetal acceleration (), measured in meters per square second, experienced by a person is defined by the following expression:
(1)
Where:
- Angular speed of the Earth, measured in radians per second.
- Distance perpendicular to the rotation axis, measured in meters.
Since rotation axis passes through poles and distance described above is directly proportional to centripetal acceleration. The person must be located in the Equator Line, which is equivalent to the radius of the planet.
In addition, the angular speed of the Earth can be calculated in terms of its period (), measured in seconds:
(2)
If we know that and
, then the maximum centripetal acceleration experienced by a person is:
The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
The mechanical energy of the system is sum of the potential and kinetic
energy of the system.
Response:
- <u>E1 increases, E2 decreases</u>
Mechanical energy, M.E. in the block and spring system can be presented as follows;
M.E. = Energy in the spring + Kinetic energy of the blocks + Energy done on friction
- Mechanical energy of the block-spring system, E1
When the blocks are held at rest;
The mechanical energy in the block-spring system when the blocks are held at rest can be found as follows;
Energy in the spring = 0
Kinetic energy of the blocks = 0
Friction energy = 0
Therefore;
E1 for the block at rest = 0
E1 when the blocks come to rest again
Energy in the spring = > 0
Kinetic energy = 0
Energy of friction = 0
Therefore;
The mechanical energy of the block-spring system, E1, increases
- The mechanical energy of the block-spring-Earth system, E2
When the blocks are held
Energy in the spring = 0
Energy done due to friction = 0
Potential energy of Block B = m·g·h
Kinetic energy of the blocks = 0
When the blocks come to rest again, we have;
Energy in the spring =
Energy received due to friction = 0
Potential energy of Block B = m·g·(h - y)
Where;
Which gives;
The energy in the spring-block-Earth system, E2, when initially held is more than the the energy when the blocks com to rest again.
Therefore, E2 decreases
The correct option is therefore;
- E1 increases, E2 decreases
