- A simple harmonic oscillator has amplitude A and period T. Find the minimum time required for its position to change from x = A to x = A/2 in terms of the period T.arrow_forwardA Physics Question is the image attachedarrow_forwardA physical pendulum consists of a disk of radius R = 2 m, whose mass is homogeneously distributed and is equal to 6 kg, is suspended just at a point on its perimeter. The puck is displaced from its equilibrium position. until it forms an angle θ = π/16 with respect to the vertical and is then released. find: a) The period of the system. b) Make a graph of angular position v/s time where the amplitude, initial phase and system period.arrow_forward
- the general solution to a harmonic oscillator are related. There are two common forms for the general solution for the position of a harmonic oscillator as a function of time t: 1. x(t) = A cos (wt + p) and 2. x(t) = C cos (wt) + S sin (wt). Either of these equations is a general solution of a second-order differential equation (F= mā); hence both must have at least two--arbitrary constants--parameters that can be adjusted to fit the solution to the particular motion at hand. (Some texts refer to these arbitrary constants as boundary values.) Part D Find analytic expressions for the arbitrary constants A and in Equation 1 (found in Part A) in terms of the constants C and Sin Equation 2 (found in Part B), which are now considered as given parameters.

Suppose it moves as a particle under constant acceleration for 4.50 s. Find (a) its position and (b) its velocity at the end of this time interval. Next, assume it moves as a particle in simple harmonic motion for 4.50 s and x = 0 is its equilibrium position. Find (c) its position and (d) its velocity at the end of this time interval.arrow_forwardA buoy floating in the ocean is bobbing in simple harmonic motion with amplitude 6 ft and period 8 seconds.

- Ex. 16 : A particle performing S.H.M. has a velocity of 10 m/s, when it crosses the mean position. If the amplitude of oscillation is 2 m, find the velocity when it is midway between mean and extreme position.arrow_forward(a) As an illustration of action angle variables to find frequency, consider a linear harmonic oscillation and prove that its frquency v is V= 1 μ 2π V marrow_forwardThe oscillatory movement of a simple pendulum is a characteristic of the regular repetition of displacements around an equilibrium position. The pendulum swings due to the restored force of gravity, which seeks to bring the mass back to the equilibrium point. The oscillatory behavior is described by a trigonometric solution, which relates the pendulum's position to time, considering its amplitude, frequency and initial phase. Statement: A simple pendulum moves according to the following question:y(t) = A.sin(ωt + φ)In this question, y(t) is the horizontal position of the pendulum, A is its amplitude, ω is its angular velocity, given by ω = 2πf, and φ is the initial phase of the movement, in radians. Since the initial phase of the movement is equal to 0 and its angular velocity is π/2 rad/s, the oscillation frequency of this pendulum is correctly given by the alternative: a) 2.0Hz b) 1.5Hz c) 1.0Hz d) 0.5Hz e) 0.25Hzarrow_forward
