The force constant of the spring is determined as 14,222.2 N/m.

<h3>Force constant of the spring</h3>

Apply the principle of conservation of energy,

K.E = U

where;

  • K.E kinetic energy of the elevator
  • U is elastic potential energy of the spring

¹/₂mv² = ¹/₂kx²

mv² = kx²

k = mv²/x²

Where;

  • m is mass of the elevator
  • v is speed
  • x is compression of the spring

k = (2000 x 8²)/(3²)

k = 14,222.2 N/m

Thus, the force constant of the spring is determined as 14,222.2 N/m.

To test the quality of a tennis ball, you drop it onto a floor from a height of 4.00m . It rebounds to a height of 2.00 m. If th
Agata [3.3K]
In this problem, we apply the equation regarding  kinematics  expressed as  vf^2 = v0^2 + 2as  vf eventually becomes zero because the ball stops in the end. a = -9.8 m/s2s = 2 metres this time 
This gives initial velocity, vo equal to 6.26m/s 
now 6.26-(-8.85) = 15.11m/s 

change in velocity/change in time = average acceleration 15.11/(12/1000) = 1259.167 m/s^2

An astronaut has a mass of 100 kg and has a weight and if 370 N on Mars. What is the gravitational strength on Mars?
Reika [66]

Answer:

3.7 N/kg

Explanation:

The gravitational strength refers to the amount of gravity acting per unit mass. Hence in this case,

Gravitational Strength = Weight / Mass

= 370 / 100

= <u>3</u><u>.</u><u>7</u><u>N</u><u>/</u><u>k</u><u>g</u>

1.) if you are sitting still are you accelerating? How do you know?
castortr0y [4]

yes. gravity is working on you and everything on you.

also earth is rotating


no not in respect ofimmediate surroundings

object could move at constant velocity = no change in either magnitude or direction

change of position "proves" this

Consider two tubes filled with water at the same height, one with fresh water and the other tube with salt water. The pressure i
Olegator [25]

Answer:

B

Explanation:

The correct option for the question is B that is salt water. In salt water, the density of water is higher so the pressure at the end of tube containing salt water will be greater. As according to the hydrostatic law the pressure at a given point will be directly proportional to the distance travelled as well.
