As a train accelerates away from a station, it reaches a speed of 4.7 m/s in 5 s. if the train’s acceleration remains constant, what is its speed after an addition 6 s has elapsed

5.64

Explanation:

if in 5 s it reached 4.7 m/s then in 1 s it would reach .94 m/s. and .94 mps every second for 6 seconds adds up to 5.64 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
