Question

A 3.5 kg mass compresses a spring with spring constant 1680 N/m by a distance 0.95 m . The spring is released and launches the mass up a frictionless ramp onto a table of height 0.5 m . The table has a rough surface with coefficient of friction 0.15. After the mass has travelled 3.5 m on the table, what is the speed of the mass?

Answer in m/s. GOOD HANDWRITING/TYPING PLEASE.

Please please rate it up, Thankyou!

A 1.1 kg mass compresses a spring by a distance 0.25 m. The mass
is released from rest. The mass travels over equal patches of rough
surfaces with coefficient of friction μk=0.15 and length 0.5m. If
the spring constant of the spring is 770 N/m, how many (including
the decimal fraction) mats does it take to stop the mass?

A 100 ? / ? constant spring horizontal spring compresses 20 ??
and is used to launch a 2.5 ?? box across a horizontal surface
without friction. After the box travels a certain distance, the
surface becomes rough. The coefficient of kinetic friction of the
box on the surface is 0.15. Determine how far the box slides on the
rough surface before stopping.

Box 1 of mass 2 kg is pressed against a spring with spring
constant 600 N/m that is initially compressed by 0.5 m. The spring
launches box 1 which then slides along a frictionless surface until
it collides with box 2 (initially at rest) with mass 3 kg. They
stick together, slide over a patch of sticky spilled soda with
coefficient of kinetic friction 0.6 and length 1.2 m. Then, they
fall off a cliff of height 3 m.

A mass of 2.1 kilograms is placed on a
horizontal frictionless surface against an
uncompressed spring with spring constant 1151.5 N/m. The
inclined portion of the surface makes at an angle
of 30 degrees to the horizontal and has a coefficient of kinetic
friction of 0.27 with the mass. The mass is pushed against the
spring until it is compressed a distance 0.15 and then released.
How high (vertically), in meters, does the mass rise from the
original height before...

A 3.00 kg mass is pushed against a spring and released. If the
spring constant of the spring is 7500 N/m and the spring is
compressed 10.0 cm. (a) What is the energy stored in the compressed
spring? (b) What is the maximum speed ?0 of the mass? (c) The mass
then travels across a rough surface and then up a smooth ramp. The
speed at the beginning of the ramp is ?1 = 4.00 m/s. What is the
work...

a crate of stuffed kittens with a mass of 1kg compresses a
spring a distance of 2.84m. The spring has a spring constant of
250N/m. The crate is released and slides across a rough surface
with a kinetic friction coefficient of 0.38 for a distance of 62m
before colliding with and sticking to another crate. The second
crate is filled with cans of smoked turkey and has a mass of 2kg.
The two crates then slide horizontally off a vertical...

A horizontal spring with spring constant 150 N/m is compressed
17 cm and used to launch a 2.9 kg box across a frictionless,
horizontal surface. After the box travels some distance, the
surface becomes rough. The coefficient of kinetic friction of the
box on the surface is 0.15.
Use work and energy to find how far the box slides across the
rough surface before stopping.
Express your answer to two significant figures and include the
appropriate units.

A block of mass m = 3.3 kg is on an inclined plane with
a coefficient of friction μ1 = 0.39, at an
initial height h = 0.53 m above the ground. The plane is
inclined at an angle θ = 44°. The block is then compressed
against a spring a distance Δx = 0.13 m from its
equilibrium point (the spring has a spring constant of
k1 = 35 N/m) and released. At the bottom of the
inclined plane...

A stationary block of mass 5 kg explodes into two pieces L and R
that slide across a frictionless floor. The left piece slides
across the region with friction and stops, the right piece
compresses a spring. Momentum is conserved during the explosion.
Piece L has a mass of 2 kg and encounters a flat surface with
coefficient of kinetic friction µL = 0.4 and slides to a stop in
distance dL = 0.5 m. Piece R slides across the...

A spring with a spring constant of 302 N/m is initially
compressed by a distance of 0.078 m from its equilibrium position.
A mass of 0.038 kg is then held against the compressed spring and
released from rest while upon a horizontal, frictionless surface.
Assuming that the spring then pushes the mass across the surface,
with speed does the mass leave the spring? Assume proper SI
Units.
