Please help!! A certain antelope once ran 1.6 km with an average speed of 67 km/h. The antelope’s speed for the first half (0.80 km) was 88 km/h. A) How long did it take to do the the 1.6 km? B) How long did it take to do the first half? C) Using your answers from the previous two parts, how long did the second half take to run? D) Lastly, what was the average speed for the second half?

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

  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
