While the elevator is moving up with constant acceleration a, is the period of the pendulum affected? If so, how? b. Now suppose we hang a particle of mass m on a spring of spring constant k and attach it to the ceiling of the same elevator. How does an upward acceleration a affect the period of this simple harmonic oscillator?arrow_forwardA particle of mass m moving in one dimension has potential energy U(x) = U0[2(x/a)2 (x/a)4], where U0 and a are positive constants.

- A block of mass m = 5.94 kg is attached to a spring with spring constant k = 1592 N/m and rests on a frictionless surface. The block is pulled, stretching the spring a distance of 0.150 m, and is held still. The block is then released and moves in simple harmonic motion about the equilibrium position. a. What is the frequency of this oscillation? b. Where is the block located 3.24 s after it is released? c. What is the velocity of the mass at that time?arrow_forward(a) What is the effect on the period of a pendulum if you double its length? (b) What is the effect on the period of a pendulum if you decrease its length by 5.00%?arrow_forward(a) A pendulum that has a period of 3.00000 s and that is located where the acceleration due to gravity is 9.79 m/s2 is moved to a location where the acceleration due to gravity is 9.82 m/s2. What is its new period? (b) Explain why so many digits are needed in the value for the period, based on the relation between the period and the acceleration due to gravity.arrow_forward
- A Two particles A and B move at a constant speed in circular paths at the same angular speed . Particle As circle has a radius that is twice the length of particle Bs circle. What is the ratio TA/TB of their periods?arrow_forwardThe equations listed in Table 2.2 give position as a function of time, velocity as a function of time, and velocity as a function of position for an object moving in a straight line with constant acceleration. The quantity vxi appears in every equation. (a) Do any of these equations apply to an object moving in a straight line with simple harmonic motion? (b) Using a similar format, make a table of equations describing simple harmonic motion. Include equations giving acceleration as a function of time and acceleration as a function of position. State the equations in such a form that they apply equally to a blockspring system, to a pendulum, and to other vibrating systems. (c) What quantity appears in every equation?arrow_forwardYour grandfather clock's pendulum has a length of 0.9930 m. a. If the clock runs slow and loses 23 s per day, how should you adjust the length of the pendulum? Note: due to the precise nature of this problem you must treat the constant g as unknown (that is, do not assume it is equal to exactly 9.80 m/s2). Express your answer to two significant figures and include the appropriate units. Enter positive value in case of increasing length of the pendulum and negative value in case of decreasing length of the pendulum.arrow_forward
