A 75 kg person is standing at the very end of a 6.0 meter long stationary raft with a mass of 225 kg that is floating frictionlessly on the water. If the person then walks with a constant velocity of 1.0 m/s all the way to the other end of the raft, how far will the raft move, and what will be the average velocity of the raft during that movement (as observed by a stationary person on shore)

  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
