Answer:
The speed is 1.52 m.
Explanation:
Given that,
Displacement =0.270 m
Distance = 0.130 m
Suppose a 0.321-kg mass is attached to a spring with a force constant of 13.3 N/m.
We need to calculate the angular velocity
Using formula of angular velocity
Put the value into the formula
We need to calculate the velocity
Using formula of velocity
Put the value into the formula
Hence, The speed is 1.52 m.
Answer:
Displacement (i.e. change in its final position)
Explanation:
In classical mechanics work is described as the displacement of the body in the direction of the applied force.
<u>Mathematically given as:</u>
where:
F = force on the body
s = displacement of the body
θ = angle between the force and direction of displacement
While force, acceleration, velocity can also be the answer for the blank space but the displacement effect is visible during and even after the work has been done, so one can notice the change in position of the object even when the person has not seen the process but just the initial condition of the body.
Answer:
Explanation:
Given
at certain point displacement and velocity is 0.345 m and 0.54 m/s
Therefore Potential and Kinetic Energy associated is
Kinetic Energy
Total Energy
Total Energy is conserved hence at maximum displacement all energy will be Potential energy
where A=maximum displacement
Maximum speed occurs at equilibrium Position where Potential Energy is zero
thus
(c)When block is at 0.2 m from Equilibrium speed then its Potential Energy is
