The figure shows the arrangement of given data.
The displacement is considered along X direction and time along Y direction.
The slope of the graph is given by tan θ
So tan θ = Δx/Δt = Velocity between those two points considered for finding slope of graph.
So slope of position time is graph is equivalent to kinematic quantity Velocity.
Answer:
1) The amplitude of the motion is approximately 0.274 meters.
2) The total energy of the object at any point of its motion is 16.892 joules.
Explanation:
1) An object under simple harmonic motion is conservative, since there is no dissipative forces acting during motion (i.e. friction, air viscosity). The amplitude of the motion can be found easily by Principle of Energy Conservation by the fact that maximum elastic potential energy (), in joules, is equal to maximum translational kinetic energy (
), in joules:
(1)
Where:
- Spring constant, in newtons per meter.
- Amplitude, in meters.
- Object mass, in kilograms.
- Speed of the object at equilibrium, in meters per second.
If we know that ,
and
, then the amplitude of the motion is:
The amplitude of the motion is approximately 0.274 meters.
2) The total energy of the object (), in joules, is found either by maximum elastic potential energy or by maximum translational kinetic energy, that is: (
,
)
The total energy of the object at any point of its motion is 16.892 joules.
