An object attached to a vertical spring is displaced 5.00 cm from rest and then released. If the mass oscillates 40.0 times in 21.7 s and the spring constant in the spring is 13.0 N/m, what is the mass of the object?

A spring has a length of 0.280 m when a 0.300 kg mass hangs from it, and a length of 0.750 m when a 2.70 kg mass hangs from it. (a) What is the force constant (in N/m) of the spring? N/m (b) What is the unloaded length (in m) of the spring? m

A mass of 0.43 kg is is initially traveling at across a horizontal surface. It then reaches a spring with a fixed end having a spring constant of 138 N/m that is positioned horizontally and initially at equilibrium. If the initial speed of the mass is 3.81 as it contacts the spring, what is the speed of the mass after compressing the by 0.153 m if the coefficient of kinetic friction is between the surfaces is 0.47 ?

24. A mass-spring system is set up so that the mass oscillates in the horizontal. The mass is 0.88_kg, and the spring has constant 45_N/m. The mass is pulled back so that the spring stretches 0.72 m, and then the mass is released. Find the speed of the mass when it is located at 0.31 m. (Assume there is no friction between the mass and the tabletop.)

A bullet with mass 4.95 g is fired horizontally into a 1.972-kg block attached to a horizontal spring. The spring has a constant 5.71 x 102 N/m and reaches a maximum compression of 6.44 cm. (a) Find the initial speed of the bullet-block system. m/s (b) Find the speed of the bullet. m/s

A mass of 0.69 kg is is initially traveling at 6.19 m/s across a horizontal, frictionless surface. It then reaches a spring with a fixed end having a spring constant of 334 N/m that is positioned horizontally and initially at equilibrium. The incoming mass will then contact the spring, compressing it as it comes to rest. What is the speed of the mass upon the spring being compressed by 0.173 m from its equilibrium position?

A spring has a length of 0.180 m when a 0.300 kg mass hangs from it, and a length of 0.750 m when a 2.10 kg mass hangs from it. (a) What is the force constant (in N/m) of the spring? N/m (b) What is the unloaded length (in m) of the spring? m

A 475.-g mass at rest on the end of a horizontal spring with spring constant 925. N/m is struck by a hammer which gives it an initial speed of 3.00 m/s. Determine the maximum acceleration (in m/s/s) that the mass experiences as it oscillates. (What equation can I use to solve the maximum acceleration?)

An oscillator is comprised of a 2.0-kg block and a 1200 N/m spring. The block is held at rest 2.5 cm from the equilibrium point and released. Assuming no friction, what is the block's maximum speed? 22 cm/s 61 cm/s 1.8 m/s 40 cm/s 87 cm/s

A 610.-g mass at rest on the end of a horizontal spring with spring constant 425. N/m is struck by a hammer which gives it an initial speed of 4.63 m/s. Determine the maximum acceleration (in m/s/s) that the mass experiences as it oscillates.
