An oscillating mass at the end of a spring is at a distance y from its equilibrium position given by
The constant k measures the stiffness of the spring.
(a) Find a time at which the mass is farthest from its equilibrium position. Find a time at which the mass is moving fastest. Find a time at which the mass is accelerating fastest.
(b) What is the period, T , of the oscillation?
(c) Find dT /dm. What does the sign of dT /dm tell you?
A 1.0 kg particle moves under the influence of the potential V(x) = - C x2 cos(3x), where C = 5 J/m2. Find the frequency of small oscillations about the equilibrium points for this particle
Consider an electron in a cyclotron motion with the velocity v = 10.000 × 105 m/s perpendicular to the magnetic field of strength B = 1.00 × 10-4 T. Find the ratio of the field created during the cyclotron motion to the external field.
