Question

A block of mass ?=4.50 kg m=4.50 kg slides along a horizontal table with velocity ? 0 =2.50 m/s v0=2.50 m/s . At ?=0 x=0 , it hits a spring with spring constant ?=43.00 N/m k=43.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.300 μ=0.300 . How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.

Answer #1

A block of mass m = 2.90 kg slides along a horizontal table with
velocity v 0 = 2.00 m/s . At x = 0 , it hits a spring with spring
constant k = 33.00 N/m and it also begins to experience a friction
force. The coefficient of friction is given by μ = 0.400 . How far
has the spring compressed by the time the block first momentarily
comes to rest? Assume the positive direction is to the...

A block of mass ?=4.80 kg slides along a horizontal table with
velocity ?0=3.00 m/s. At ?=0, it hits a spring with spring constant
?=36.00 N/m and it also begins to experience a friction force. The
coefficient of friction is given by ?=0.350. How far has the spring
compressed by the time the block first momentarily comes to rest?
Assume the positive direction is to the right.

A block of mass 13.0 kg slides from rest down a frictionless
39.0° incline and is stopped by a strong spring with
k = 2.70 ✕ 104 N/m. The block slides
3.00 m from the point of release to the point where it comes to
rest against the spring. When the block comes to rest, how far has
the spring been compressed?

0.75-kg block slides on a rough horizontal table top. Just before
it hits a horizontal ideal spring its speed is 3.5 m/s. It
compresses the spring 5.7 cm before coming to rest. If the spring
constant is 1200 N/m, the thermal energy of the block and the table
top must have:

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.

1-kg block slides along frictionless surface XY with a velocity of
v = 10 m/s. It then moves along a surface YZ with length 10 m, and
uk = 0.2 until hitting an undeformed spring whose k = 1000 N/m.
What is the block’s velocity just before it hits the
spring?
What will be the maximum compression of the spring?
After leaving the spring, will the block reach surface
XY?
If yes, compute for the velocity of the block...

A mass m = 13 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.07, for a
distance d = 5.1 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 33° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 33°
(thus on the incline it is...

A 1.40 kg block slides with a speed of 0.950 m/s on a
frictionless horizontal surface until it encounters a spring with a
force constant of 734 N/m. The block comes to rest after
compressing the spring 4.15 cm. Find the spring potential, U, the
kinetic energy of the block, K, and the total mechanical energy of
the system, E, for compressions of (a) 0 cm, (b) 1.00 cm, (c) 2.00
cm, (d) 3.00 cm, (e) 4.00 cm

Block B of 40.0 kg is sitting at a frictionless horizontal floor
at a height h1 = 40.0 m above the ground, when a second 100.0 kg
block (block A), moving at an unknown speed hits and sticks to
block B. After the collision, the combination slides down a hill
which has friction, with a speed of 2.00 m/s.
A. What was the speed of the block A before the collision?
B. At the end of the path, a very...

A 0.85 kg block slides 3.3 m across a frictionless,
horizontal table at 2.2 m/s, moving left. Once the block hits the
spring, it sticks, compressing the spring 70 cm before the block
stops and reverses direction. The block then continues to bounce
back and forth, still attached to the spring. The spring constant
is 8.4 N/m. Ignore air resistance.
(b) [3 points] Plot the velocity of the block as a
function of time, with t = 0 when the...
