Determine the velocity of a 55-kg skier whose kinetic energy is 8900 J

Kinetic energy = 1/2mv^2

8900 j =1/2*55*v^2

v^2=8900*2/55

v^2=323.6

v=17.98

Explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
