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
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.
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.
The work done is zero because the velocity is constant. Work is only done when there is a change in 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.
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.
No.
It's good to get a box spring that comes with the mattress which is matched to work perfectly together.
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.

Yes, in fact I would recommend it. Correct answer: No, they are typically designed not to use a 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.
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.
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.

Yes, It's accually made the same.
