a ball is thrown upward with an initial velocity of 4 m/s. the balls velocity after 8 seconds is what m/s?

4

Explanation:

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

total distance/total time

(85 + 82)/(5+3)

167/8
