. A 5 kg box is traveling at 10 m/s just before it hits a pillow. It takes 2 s for the box to stop. What is the force of impact provided by the pillow?
A. 100 N
B. 25 N
C. 5N
D. 4N

  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
