A block with a mass of 100 grams slides to the right at 4.0 meters per second and hits another block which has a mass of 150 grams. After the collision, block b slides to the right, and rebounds hitting block A, which slides to the left at 1.5 m/s. Calculate the speed of Block b after the collision.

  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

the right answer is 0.3 meters per second
