Mass and Spring: A 1.2 kg mass hangs in equilibrium from a spring. When the mass is displaced by 0.19 m and released from rest, it reaches a top speed of 1.2 m/s as it oscillates. A group of students records the motion of the spring for 321 seconds and deduces the system has a quality factor of Q = 1248. (a) What is the period of oscillation? (b) What is the spring constant of the spring?

Physics A 3.0 kg mass hangs in equilibrium from a spring. When the mass is displaced by 0.09 m and released from rest, it reaches a top speed of 1.8 m/s as it oscillates. A group of students records the motion of the spring for 253 seconds and deduces the system has a quality factor of Q = 2500. (a) What is the period of oscillation? (b) What is the spring constant of the spring

A 43 kg mass on the end of a spring with spring constant k = 1,470 oscillates with simple harmonic motion x = A cos (@t+@). Find the minimum time taken in seconds (to 3 decimal points) for the mass to travel from 0.81A to 0.54A.

A 0.4 kg block hangs from a spring with a spring constant of 17  N/m. At t=0s the block is 0.3  m below the equilibrium point and moving upward with a speed of  1.6  m/s. What is the block's oscillation frequency (in Hz)?

A block of mass  m = 6.04 kg  is attached to a spring with spring constant  k = 1532 N/m  and rests on a frictionless surface. The block is pulled, stretching the spring a distance of 0.145 m, and is held still. The block is then released and moves in simple harmonic motion about the equilibrium position.

(Give the displacement from the equilibrium. Include the sign of the value in your answer.) m(c) What is the velocity of the mass at that time? (Indicate the direction with the sign of your answer.) m/s

Part 2) An organ pipe of length L = 4.6 m is open at both ends. It is driven to oscillate with a standing wave that has two nodes within the pipe. (a) What is the wavelength of the standing wave? m (b) If the speed of sound in air is 330m/s, what is the frequency that the organ pipe is oscillating at in this mode? Hz

A mass of 7.2 kg is attached to a spring with the spring constant 30.0 N-m¹ and is placed on a frictionless surface with the spring attached to a wall. The spring is then compressed by 0.03 m and released to oscillate with simple harmonic motion. Calculate the absolute value of maximum velocity of the mass on spring. Provide your answer in Sl units.
