some basic physics will tell you that the mass of the box times acceleration due to gravity times the height of the box above the ground, minus the force of the spring or the spring constant times the distance the spring stretches will equal .5 times the mass of the box times the velocity squared mgh-kx=.5mv2

A metal box is attached to a small parachutes dropped by a helicopterexplain in terms of force why its velocity increases immediately after being dropped?
When the box is dropped from the helicopter, it experiences a downward force due to gravity. At the same time, air resistance acting in the opposite direction slows down the box. When the parachute is released, it creates air resistance that counters the force of gravity, allowing the box to accelerate and increase its velocity.
Is it gravitational energy in the spring of a jack in the box?
No, the energy stored in the spring of a jack-in-the-box is potential energy due to the compression of the spring. When the spring is released, this potential energy is converted into kinetic energy and gravitational potential energy as the jack pops out of the box and moves upwards due to gravity.
Boy is pushing a 30 kg box across the floor at a constant velocity of 0.5 ms. How much work in Joules is done by the boy on the box if the velocity change to 1.0 ms?
The work done is zero because the velocity is constant. Work is only done when there is a change in velocity.
How much air resistance acts on a falling 100-N box of nails when it reaches terminal velocity?
At terminal velocity, the air resistance acting on the falling 100-N box of nails would be equal in magnitude to the weight of the box, or 100 N. This means that the net force acting on the box would be zero, resulting in a constant velocity.
The box decelerates at a rate of 3 m s and skids 24 meters before coming to a stop How fast were you traveling when the box fell out?
To find the initial velocity of the box when it fell out, you can use the formula: final velocity squared = initial velocity squared + 2 * acceleration * distance. Given that the final velocity is 0 m/s, acceleration is 3 m/s^2, and distance is 24 meters, you can solve for the initial velocity.
Does two twin box spring equal a queen box spring?
No.
What is special about a box spring with a low profile?
It's good to get a box spring that comes with the mattress which is matched to work perfectly together.
Why buy low profile box spring?
A low profile box spring is a box spring of minimal depth used on platform beds where a regular box spring would cause the bed to sit higher than desired.
What is box spring in spanish?
boxspring
Can you use a box spring with a platform bed?
Yes, in fact I would recommend it. Correct answer: No, they are typically designed not to use a box spring.
What is a split queen box spring?
It is used when you can not fit a standard queen box spring into the door of a room, or upstairs in an elevator etc.
How much does a queen box spring weigh?
The weight of a queen size box spring will vary depending on the materials used. The average weight of a queen size box spring would usually be between 60 and 100 pounds.
When is kinetic energy for a match box car zero?
Kinetic energy = ½ * mass * velocity^2 The mass doesn't change as the match box car moves around, but when it stops velocity =0. When the velocity = 0. KE = 0.
Is it gravitational energy in the spring of a jack in the box?
No, the energy stored in the spring of a jack-in-the-box is potential energy due to the compression of the spring. When the spring is released, this potential energy is converted into kinetic energy and gravitational potential energy as the jack pops out of the box and moves upwards due to gravity.

Is a low profile box spring as good as a regular box spring for a king size mattress?
Yes, It's accually made the same.
