Final answer:

The final temperature of the ice sample is 0°C.

Step-by-step explanation:

To find the final temperature, we can use the equation:

Q = mcΔT

Where Q is the thermal energy added to the ice, m is the mass of the ice, c is the specific heat capacity of ice, and ΔT is the change in temperature.

In this case, the thermal energy added to the ice is 4584000 J and the mass of the ice is 10.9 kg. The specific heat capacity of ice is 2090 J/kg°C. We can rearrange the equation to solve for ΔT:

ΔT = Q / (mc)

Plugging in the values, we get:

ΔT = 4584000 J / (10.9 kg * 2090 J/kg°C)

Calculating the value, we find that ΔT is approximately 21.9°C. Since the ice was initially at -21.9°C, we can find the final temperature by adding the change in temperature to the initial temperature:

Final temperature = -21.9°C + 21.9°C = 0°C

Therefore, the final temperature of the sample is 0°C.
