Answer:
Explanation:
From first law of thermodynamics
Q = ΔE + W
Q is heat added , ΔE is increase in internal energy and W is work done.
Here Q = - 963.6 kJ , - ve sign because head is absorbed
ΔE - 2836 kJ , negative sign given ( gas cooled )
Putting these values in the equation above
- 963.6 = - 2836 + W
W = 2836 - 963.6 kJ
= 1872.4 kJ .

Answer:
a = Δv/t = (vf - vi)/t = (0 - 5)/4 = -1.25 m/s²
Explanation:
You may or may not need the negative sign, depending on how the question designer was thinking about the problem.
