When a 0.184 - kg mass is attached to a vertical spring, it causes the spring to stretch a distance d. If the mass is now displaced slightly from equilibrium, it is found to make 75.0 oscillations in 11.6 s. Find the stretch distance, d.

An oscillator consists of a block of mass 0.500 kg connected to a spring.  When set into oscillation with amplitude 35.0 cm, the oscillator repeats its motion every 0.500 s.  Find the spring constant.

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.

You cut the tail spring off and meausre the spring force constaant and determine it to be 42.5 N/m. If you apply a 1.35 kg mass to the spring, what will be the period of oscillation?

At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with an amplitude of 20.0 cm. It is observed that the maximum speed of the bunch of bananas is 42.2 cm/s. What is the weight of the bananas in newtons?

A student stretches a spring, attaches a 1.90 kg mass to it, and releases the mass from rest on a frictionless surface. The resulting oscillation has a period of 0.910 s and an amplitude of 28.0 cm. Determine the oscillation frequency, the spring constant, and the speed of the mass when it is halfway to the equilibrium position.

A 0.20 kg ball is tied to a string.  It is pulled to an angle of 8.00º and released to swing as a pendulum.  At student with a stopwatch finds that 10 oscillations take 12 s.  How long is the string?  Use g = 10 m/s/s.
