2. A person drives 3 km West. The person then turns around and travels 1 km East. Finally,

the person travels 2 km East. The total trip takes 2 hours.

a) Sketch the motion of the person. Clearly label positions (number and units) and

directions throughout the bear's trip.

Also, label displacement vectors with magnitudes during the person's trip.

d) What is the person's average speed?

e) What is the person's average velocity? (Include magnitude and direction.)

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

  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

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
