Answer #1

If you have any doubt in any part of the solution, feel free to ask.

A massless spring of spring constant k = 4872 N/m is
connected to a mass m = 210 kg at rest on a horizontal,
frictionless surface.
Part (a) The mass is displaced from equilibrium
by A = 0.73 m along the spring’s axis. How much potential
energy, in joules, is stored in the spring as a result?

the displacement A= 0.73 m, how much time, in seconds, is
required for...

The potential energy stored in a spring is
1/2kx2, where k is the force constant
of the spring and x is the distance the spring is
stretched from equilibrium. Suppose a spring with force constant
300 N/m is stretched by 10.0 cm, placed in 40 g of water in an
adiabatic container, and released. The mass of the spring is 20 g,
and its specific heat capacity is 0.30 cal/(g °C). The initial
temperature of the water and the spring...

A sphere is attached to a vertical spring of constant k = 11,990
N/m. As the sphere is allowed to hang from the spring, it also is
partially submerged in water, where 60% of its volume is
underwater. When the sphere is in equilibrium, it has displaced the
spring by 10.0 cm from its relaxed length. The density of the
sphere is 4250 kg/m3. (a) Has the spring stretched or compressed?
Explain. (b) What is the radius of the sphere?

The potential energy stored in a spring is
1/2kx2, where k is the force constant
of the spring and x is the distance the spring is
stretched from equilibrium. Suppose a spring with force constant
150 N/m is stretched by 10.0 cm, placed in 10 g of water in an
adiabatic container, and released. The mass of the spring is 20 g,
and its specific heat capacity is 0.30 cal/(g °C). The initial
temperature of the water and the spring...

A certain spring has a spring constant k1 =
420 N/m as the spring is stretched from x = 0 to
x1 = 34 cm. The spring constant then changes to
k2 = 330 N/m as the spring is stretched to
x2 = 79 cm. From x2 = 79 cm
to x3 = 97 cm the spring force is constant at
F3 = 120 N.
(a) Use the area under the curve to calculate
the work, in joules, necessary to...
