the position of a mass oscillating on a spring is given by x=(7.8cm)cos(2pi/0.68s). a) what is the frequency of this motion? b)When is the mass first at the position x=-7.8cm?

The time, t seconds, it takes a pendulum to complete one back and forth swing can be determined by the equation t = 0.32√T, where is the length of the pendulum in inches. Determine the length of the pendulum if it takes 1.5 s to make a complete back and forth swing. Select one: a. 2.17 in Ob. 21.97 in c. 2.34 in Od. 4.69 in . .

A novelty clock has a 0.0145 kg-mass object bouncing on a spring that has a force constant of 1.25 N/m. (a) What is the maximum velocity of the object if the object bounces 3 cm above and below its equilibrium position? (b) How many joules of kinetic energy does the object have at its maximum velocity?

A small fly of mass 0.8 g is caught in a spider's web. The web oscillates predominantly with a frequency of 10 Hz. At what frequency (in Hz) would you expect the web to oscillate if an insect of mass 0.5 g were trapped? (What equation can I use to find the frequency at which it ocilates?)

A simple pendulum has a bob that weighs 1.50 kg suspended from the end of a light weight cord. If this bob oscillates at a frequency of 0.750 Hz then what is the length of the cord?
