In a physics lab, you attach a 0.200 kg air-track glider to the end of an ideal spring of negligible mass and start it oscillating. The elapsed time from when the glider first moves through the equilibrium point to the second time if moves through that point is 2.60 s. Find the spring's force constant (k).

A horizontal spring attached to a wall has a force constant of 720 N/m. A block of mass 1.90 kg is attached to the spring and oscillates freely on a horizontal, frictionless surface as in the figure below. The initial goal of this problem is to find the velocity at the equilibrium point after the block is released.   (a) What objects constitute the system, and through what forces do they interact?   (b) What are the two points of interest?   (c) Find the energy stored in the spring when the mass is stretched 6.40 cm from equilibrium and again when the mass passes through equilibrium after being released from rest. x = 6.40 _____ J x = 0  ______J   (e) Substitute to obtain a numerical value.   (f) What is the speed at the halfway point?

Answer For G, H, and I

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

A simple harmonic oscillator consists of a 1.20 kg block attached to a spring. The block is ocillating back and forth along a straight line on a frictionless horizontal surface. A plot of the position of the block (in cm) as a function of time (in seconds) is shown below. What are (a) the spring constant of the spring and (b) the maximum speed and maximum acceleration of the block? (c) What is the velocity of the block at t = 1.50 s? 4. 3- 2- -2- -3- -4- -5+ 0.2 0.4 0.6 0.8 Position (cm)

A block attached to a spring, oscillates on a frictionless horizontal surface with a period of 0.45 s. The time needed by the block to move (for the first time) from position x = A to x = -A/2 is:

An initially 'un-compressed' spring (x1=0) is observed to compress 0.4 m before stopping and reversing the 26 m/s horizontal velocity of a 100 kg mass. Determine the spring constant in N/mm.
