The coefficient of kinetic friction is  ∪ = 3.699

What is Kinetic Energy?

The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

Given,

m = 50 kg

Force = 2.30 x 10^2 = 230N

Distance = 5.55m

Work done = 2.50 x 10^2 = 250 j

Using work energy principle:

F x d - ∪ x m x d = work done

230 x 5.55 -  ∪ x 50 x 5.55 = 250

1276.5 -  ∪ x 277.5 = 250

1276.5 - 250 =  277.5∪

1026.5 = 277.5 ∪

∪ = 1026.5 / 277.5

∪ = 3.699

Hence,  the coefficient of kinetic friction is ∪ = 3.699

What information do we know about the known exoplanets? a. estimates of orbits and masses b. complete composition c. precise mas
LenKa [72]

<em>The correct option is </em><em>A</em>. The information we know about the known exoplanets is estimates of orbits and masses.

<h3>What is exoplanets?</h3>

An exoplanet or extrasolar planet is a planet outside the Solar System.

In other words, exoplanet is any planet beyond our solar system.

<h3>Characteristics of exoplanets</h3>

exoplanets are known for the following characteristics;

  • they are usually hot
  • they can orbit their stars so tightly that a “year” lasts only a few days
  • they can orbit two suns at once

Thus, the information we know about the known exoplanets is estimates of orbits and masses.
