The initial velocity of the train is 12.56 m/s.
<h3>
Initial velocity</h3>
The initial velocity of the train can be determined by using the first kinematic equation as shown below;
v = u + at
u = v - at
where;
- v is the final velocity = 110 km/h = 30.56 m/s
- u is the initial velocity
u = 30.56 - (36 x 0.5)
u = 12.56 m/s
Thus, the initial velocity of the train is 12.56 m/s.

I think the answer is the sun
False i’m not too sure but hope i helped<3
Answer:
The work required to cause this volume change is 2 x 10⁶ J
Explanation:
Given;
constant pressure of the gas, P = 100 kPa = 100,000 Pa
change in volume of the gas, ΔV = 20 m³
The work required to cause this volume change is calculated as;
W = PΔV
Substitute the given values and solve for the required work (W).
W = (100,000)(20)
W = 2 x 10⁶ J
Therefore, the work required to cause this volume change is 2 x 10⁶ J
