Distance s=829.586 m
Explanation:
The initial velocity of the train is u=10 km/hr=
The final velocity of the train is v=40 km/hr=
The time taken by the train is t=2 min=120 sec
Let the distance traveled by the train during acceleration be s
The acceleration of the train is,
From the equation of motion
60 times 10 =600 well if u multiply 60 times 10 it will=600
Answer:
581 kJ, work was done by the system
Explanation:
According to the first law of thermodynamics:
where
is the change in internal energy of the system
Q is the heat absorbed by the system (positive if absorbed, negative if released)
W is the work done by the system (positive if done by the system, negative if done by the surrounding)
In this problem,
Therefore the work done by the system is
And the positive sign means the work is done BY the system.
