Question

A mass of 8 kg stretches a spring 16 cm. The mass is acted on by an external force of 7sin(t/4)N and moves in a medium that imparts a viscous force of 3 N when the speed of the mass is 6 cm/s.If the mass is set in motion from its equilibrium position with an initial velocity of 4 cm/s, determine the position u of the mass at any time t. Use 9.8 m/s^2 as the acceleration due to gravity. Pay close attention to the units. Leave answer in terms of exact numbers(no decimals).

Answer #1

Problem in answer then comment below.. i will help you..

.

**please thumbs up for this solution..thanks.**

**.**

**here i take c2 in decimal form...because value of c2 is
very typical in exact form ..**

**comment below..if any problem ok**

3. A mass of 5 kg stretches a spring 10 cm. The mass is acted on
by an external force of 10 sin(t/2) N (newtons) and moves in a
medium that imparts a viscous force of 2 N when the speed of the
mass is 4 cm/s. If the mass is set in motion from its equilibrium
position with an initial velocity of 3 cm/s, formulate the initial
value problem describing the motion of the mass. Then (a) Find the...

A mass of 1 kg stretches a spring 9.8 m. The mass is acted on by
an external force of 4 cos(t) N. If the mass is set in motion from
its equilibrium position with a downward velocity of 2 m/s, find
the position of the mass at any time. Identify the transient (i.e.,
complementary) and steady state (i.e., particular) solutions. Does
the motion exhibit resonance or a beat?

A mass weighing 16 pounds stretches a spring 8/3 feet. The mass
is initially released from rest from a point 3 feet below the
equilibrium position, and the subsequent motion takes place in a
medium that offers a damping force that is numerically equal to 1/2
the instantaneous velocity. Find the equation of motion x(t) if the
mass is driven by an external force equal to f(t) = 10 cos(3t).
(Use g = 32 ft/s^2 for the acceleration due to...

A mass of 100 g stretches a spring 5 cm. If the mass is set in
motion from its equilibrium position with a downward velocity of 10
cm/s, and if there is no damping, determine the position u
of the mass at any time t. (Use g = 9.8
m/s2 for the acceleration due to gravity. Let
u(t), measured positive downward, denote the displacement in meters
of the mass from its equilibrium position at time t

A spring is stretched by 9 in by a mass weighing 18 lb. The mass
is attached to a dashpot mechanism that has a damping constant of
0.15 lb⋅s/ft and is acted on by an external force of 6cos(8t)
lb.Determine the steady state response of this system. Use 32
ft/s^2 as the acceleration due to gravity. Pay close attention to
the units. Leave answer in terms of exact numbers(no decimals).

A mass of 1.5 kg stretches a spring 0.05 mm. The mass is in a
medium that exerts a viscous resistance of 240 NNwhen the mass has
a velocity of 6 msms. The viscous resistance is proportional to the
speed of the object.
Suppose the object is displaced an additional 0.06 mm and
released.
Find an function to express the object's displacement from the
spring's natural position, in mm after tt seconds. Let
positive displacements indicate a stretched spring, and...

A mass of 50 g stretches a spring 1.568 cm. If the mass is set
in motion from its equilibrium position with a downward velocity of
40 cm/s, and if there is no damping, determine the position u of
the mass at any time t.

A mass weighing 19.6 N stretches a spring 9.8 cm. The
mass is initially released from
a point 2/3 meter above the equilibrium position with a downward
velocity of 5
