A0.14-kg apple falls off a tree branch that is 2.6 m above the thick grass. the apple sinks 0.067 m into the grass while stopping.
1) determine the average contact force that the grass alone exerts on the apple while stopping it. ignore air resistance.

  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

i think it would be 5

the answer is 12 as i may remember
