Question

A box with a mass of 1.386 kilograms collides head-on with a
spring constant of 1.26 m*N. When the box stopped, the spring was
compressed by 25.05 centimeters.

The kinetic friction coefficient between the box and the floor is
0.484 and the gravitational acceleration is 9.8 m/s2. At this
point, obtain the speed (m/s) of the box just before it comes into
contact with the spring.

Answer #1

**Value
of spring constant is not clearly given...**

A horizontal spring with spring constant 250 N/m is compressed
by 20 cm and then used to launch a 250 g box across the floor. The
coefficient of kinetic friction between the box and the floor is
0.23.
What is the box's launch speed?

A block with a mass m = 2.12 kg is pushed into an ideal spring
whose spring constant is k = 3810 N/m. The spring is compressed x =
0.069 m and released. After losing contact with the spring, the
block slides a distance of d = 2.07 m across the floor before
coming to rest.
a) Write an expression for the coefficient of kinetic friction
between the block and the floor using the symbols given in the
problem statement...

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 spring with a spring constant of 5000 N/m is compressed 25 cm
by a mass of 2 kg. The mass is released and the spring propels the
mass across the floor. After the mass leaves the spring it
experiences drag on the floor. The kinetic coefficient of friction
between the mass and the floor 0.25.

How far does the cart slide before it come to a stop?

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...

Mary applies a force of 75 N to push a box with an acceleration
of 0.43 m/s2. When she increases the pushing force to 81 N, the
box's acceleration changes to 0.63 m/s2. There is a constant
friction force present between the floor and the box. (a) What is
the mass of the box? kg (b) What is the coefficient of kinetic
friction between the floor and the box?
(a) What is the mass of the box?
_________kg
(b) What...

a 1kg box is placed in front of a spring that has a spring force
constant of 1000 N/m. The spring is compressed 50 cm and the box is
placed in front of the spring. The spring is then released and the
1kg box slides along the horizontal, frintionless surface until it
collides and sticks to a 2 kg box which is initially at rest. what
is the speed of the boxes after the collision?

A 1 kg. box is given a push so that it slides across the floor.
How far will it go, given that the coefficient of kinetic friction
is 0.31 and the push imparts at initial speed of 3.1 m/s? Calculate
to one decimal. Use g = 9.8 m/s2

A 1 kg. box is given a push so that it slides across the floor.
How far will it go, given that the coefficient of kinetic friction
is 0.19 and the push imparts at initial speed of 5.4 m/s? Calculate
to one decimal. Use g = 9.8 m/s2

One end of a horizontal spring with force constant 130.0 N/m N /
m is attached to a vertical wall. A 5.00-kg k g block sitting on
the floor is placed against the spring. The coefficient of kinetic
friction between the block and the floor is μk μ k = 0.400. You
apply a constant force F⃗ F → to the block. F⃗ F → has magnitude
81.0 N N and is directed toward the wall. The spring is compressed...
