A mass M attached to a spring oscillates with a period of 2 s. If the mass is increased by 2 kg the period increases by one sec. Find the initial mass M assuming that Hooke's law is obeyed. (1979)

You exert a 183 N push the leftmost of two identical blocks of mass 262 g connected by a spring of stiffness 570 kg/s?. After pushing the block a distance 15 cm, you release it; by this time the rightmost block has moved a distance 5 cm. (a) What is the energy in the oscillations between the blocks? (b) What is the speed of the center of mass after the push? (c) What is the initial relative speed between the blocks? (d) What is the amplitude of the oscillation? (e) What are the fastest as slowest linear speeds of the blocks? Fastest: Slowest:

vezsion1. Question 1: A mass m attached to a horizontal spring of spring constant k is oscillating on a frictionless surface. If this mass-spring system makes 180 oscillations during a time interval of 6 minutes, then the frequency of oscillations is:

Two springs are joined and connected (in series) to a block of mass m that is set oscillating over a frictionless floor with spring constant k₁ and k₂. a) What is the frequency of the oscillation? b) What is the period of oscillation? m

The diaphragm of a loudspeaker oscillates in order to produce sound. The amplitude of such an oscillation has been found to be 5.00 am. (a) At what frequency will the magnitude of the diaphragm's acceleration be equal to g. (b) What will the effect be on the acceleration if the frequency is doubled. Explain your answer.

A 90.0-kg skydiver hanging from a parachute bounces up and down with a period of 1.50 s. What is the new period of oscillation when a second skydiver, whose mass is 60.0 kg, hangs from the legs of the first, as shown.

When taking my pet turkey to the vet, the scale read a mass of 29 kg. The scale consists of a spring that has a force constant value of 36000 N/m.   Part (a)  What distance did the spring move when the pet turkey jumped onto the scale?  d=     m    Part (b)  Assuming that the spring behaves as a simple harmonic oscillator, what is the oscillation frequency of the spring when the pet turkey steps on the scale?  f =    Hz
