Question

A block of mass *m* = 4.5 kg is attached to a spring with
spring constant *k* = 610 N/m. It is initially at rest on an
inclined plane that is at an angle of *θ* = 29° with respect
to the horizontal, and the coefficient of kinetic friction between
the block and the plane is *μ _{k}* = 0.13. In the
initial position, where the spring is compressed by a distance of

b If the spring pushes the block up the incline, what
distance, *L* in meters, will the block travel before coming
to rest? The spring remains attached to both the block and the
fixed wall throughout its motion.

Answer #1

A block of mass m = 0.53 kg attached to a spring with force
constant 119 N/m is free to move on a frictionless, horizontal
surface as in the figure below. The block is released from rest
after the spring is stretched a distance A = 0.13 m. (Indicate the
direction with the sign of your answer. Assume that the positive
direction is to the right.)
The left end of a horizontal spring is attached to a vertical
wall, and...

A wooden block with mass 1.30 kg is placed against a compressed
spring at the bottom of a slope inclined at an angle of 35.0 ∘
(point A). When the spring is released, it projects the block up
the incline. At point B, a distance of 7.95 m up the incline from
A, the block is moving up the incline at a speed of 5.75 m/s and is
no longer in contact with the spring. The coefficient of kinetic
friction...

A 2.90 kg block on a horizontal floor is attached to a
horizontal spring that is initially compressed 0.0340 m . The
spring has force constant 850 N/m . The coefficient of kinetic
friction between the floor and the block is 0.42 . The block and
spring are released from rest and the block slides along the
floor.

What is the speed of the block when it has moved a distance of
0.0190 m from its initial position?...

A wooden block with mass 1.80 kg is placed against a compressed
spring at the bottom of a slope inclined at an angle of 34.0 ?
(point A). When the spring is released, it projects the block up
the incline. At point B, a distance of 6.00 m up the incline from
A, the block is moving up the incline at a speed of 6.45 m/s and is
no longer in contact with the spring. The coefficient of kinetic
friction...

A block with mass m1 = 8.8 kg is on an incline with
an angle θ = 40° with respect to the horizontal. For the first
question there is no friction, but for the rest of this problem the
coefficients of friction are: μk = 0.38 and
μs = 0.418.
1. When there is no friction, what is the magnitude of the
acceleration of the block?
2. Now with friction, what is the magnitude of the acceleration
of the block...

A block of mass m = 0.79 kg is attached to a spring with force
constant 123.0 N/m. The block is free to move on a frictionless,
horizontal surface as shown in the figure. The block is released
from rest after the spring is stretched a distance A = 0.10 m to
the right. What is the potential energy of the spring/block system
0.25 s after releasing the block?

A block of mass m = 1.5 kg is attached to a massless,
frictionless vertical spring and stretches the spring by an amount
y0 = 0.15m
a)find the spring constant k of the spring
b) the block is then pulled down by an additional 0.05m below
its equilibrium position and is released. express the position of
the block during its resulting simple harmonic motion using the
equation y(t) = ymcos([email protected]).
c) find the maximum acceleration fo the block A(m).

An inclined plane of angle θ = 20.0° has a spring of force
constant k = 495 N/m fastened securely at the bottom so that the
spring is parallel to the surface as shown in the figure below. A
block of mass m = 2.29 kg is placed on the plane at a distance d =
0.297 m from the spring. From this position, the block is projected
downward toward the spring with speed v = 0.750 m/s. By what...

A spring (k = 100 N/m) is fixed at the top of a plane
inclined at angle θ = 45°. A 2.0 kg block is projected up
the plane, from an initial position that is distance d =
0.70 m from the end of the relaxed spring, with an initial speed of
6.00 m/s. The coefficient of kinetic friction between the block and
the plane is 0.2 (a) What is the speed of the block at the instant
it has...

A block of mass ? = 12.0 kg is released from rest on an incline
angled at θ = 30 degrees. The block slides down and incline of
length ? = 1.40 m along the incline, which has a coefficient of
kinetic friction between the incline and the block of ?? = 0.180.
The block then slides on a horizontal frictionless surface until it
encounters a spring with a spring constant of ? = 205 N/m. Refer to
