A 30 kg box is dragged by a rope across a rough patch of ice. Despite the rope exerting a tension force of 50 N, it slows at a rate of 0.2 m/s/s.
Determine the force of friction acting on the box.

  the unit of the measure = [tex]\frac{j}{kgk}[/tex]

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 [tex]\frac{j}{kgk}[/tex]

0.19 m/s and 0.45 m/s
