A 0.40-kg mass is attached to a spring with a force constant of k = 277 N/m, and the mass–spring system is set into oscillation

valentina_108 [34]

To solve this problem it is necessary to apply the concepts related to the kinetic energy expressed in terms of simple harmonic movement, as well as the concepts related to angular velocity and acceleration and linear acceleration and velocity.

By definition we know that the angular velocity of a body can be described as a function of mass and spring constant as

$\omega = \sqrt{\frac{k}{m}}$

Where,

k = Spring constant

m = mass

From the given values the angular velocity would be

$\omega = \sqrt{\frac{277}{0.4}}$

$\omega = 26.31rad/s$

The kinetic energy on its part is expressed as

$E = \frac{1}{2} m\omega^2A^2$

Where,

A = Amplitude

$\omega$ = Angular Velocity

$m = Mass$

PART A) Replacing previously given values the energy in the system would be

$E = \frac{1}{2} m\omega^2A^2$

$E = \frac{1}{2} (0.4)(26.31)^2(3*10^{-2})^2$

$E= 0.1245J$

PART B) Through the amplitude and angular velocity it is possible to know the linear velocity by means of the relation

$v = A\omega$

$v = (3*10^{-2})(26.31)$

$v = 0.7893m/s$

PART C) Finally, the relationship between linear acceleration and angular velocity is subject to

$a = A\omega^2$

$a = (3*10^{-2})(26.31)^2$

$a = 20.76m/s^2$

A child blows a leaf from rest straight up in the air. The leaf has a constant upward acceleration of magnitude 1.0\,\dfrac{\tex

Novosadov [1.4K]

Answer:

Explanation:

Given

Acceleration a = 1.0m/s²

Displacement S = 1.0m

Required

Time t taken by the leaf to displace

Using the equation of motion

S = ut+1/2at²

Substitute

1.0 = 0+1/2(1)t²

1 = t²/2

Cross multiply

t² = 2

t = ±√2

t = 1.41secs

It takes the leaf to 1.41s to displace by 1m upward
