Acheetah can accelerate from rest to a speed of 21.5 m/s in 6.75 s. what is its acceleration? m/s^2

Explanation:

Acceleration is the change in velocity for a given period of time, we can express this in the next formula:

In this case the values are:

Inserting known values, the acceleration is:

  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

cant without the picture! ?
