¡Hellow!
For this problem, first, lets convert the seconds in hours:
5,4x10³ 5400
h = sec / 3600
h = 5400 s / 3600
h = 1,5
Let's recabe information:
d (Distance) = 386 km
t (Time) = 1,5 h
v (Velocity) = ?
For calculate velocity, let's applicate formula:
Reeplace according we information:
386 km = v * 1,5 h
v = 386 km / 1,5 h
v = 257,33 km/h
The velocity of the train is of <u>257,33 kilometers for hour.</u>
<u></u>
Extra:
For convert km/h to m/s, we divide the velocity of km/h for 3,6:
m/s = km/h / 3,6
Let's reeplace:
m/s = 257,33 km/h / 3,6
m/s = 71,48
¿Good Luck?

The ball will go to the right cause the car is swerving to the left so the direction of the car going to the left the ball will roll to the right side of the vehicle.
I would think the answer would be c
a. Final pressure= 5atm
b. Work done = 5000 Joules
<h3>How to determine the parameters</h3>
Given;
- Temperature = 330K
- P1 = 6 atm
- V1 = 500cm^3
- V2 = 1500cm^2
In adiabatic expansion, temperature is constant
P1V1 = P2V2
Now, let's substitute the values into the formula
6 × 500 = 1500 P2
300 = 1500P2
Make 'p2' subject of formula
P2 = 1500/300
P2 = 5 atm
The formula for work done is given as:
Workndone = P ∆ volume
Work done = 5 × ( 1500 - 500)
Work done = 5 × 1000
Work done = 5000 Joules
