The passenger is 2.3 m away from the door after 3 seconds
Since both train and passenger is moving with a constant acceleration so we can use the second equation of motion to calculate the distance cover by train and the passenger,
Distance cover by the train in 3 seconds
S=ut-0.5at^2
S=0*3-0.5*0.6*3^2=2.7 m
Distance cover by passenger in 3 seconds
S=0*3-0.5*1.2*3^2=5.4 m
Now distance of passenger from the train
s=5+2.7-5.4=2.3 m
Therefore after 3 seconds passenger is 2.3 m away from the door.
The expression, in terms of defined quantities and g is therefore Fu =((mg/2) +2 mp) g
<h3>
What is a Scale?</h3>
This can be defined as a balance or any of various other instruments or devices for weighing.
The expression in terms of defined quantities and g, for the force that the scale under left pillar shows that Fu =((mg/2) +2 mp) g .

It consists of our Solar system. Also, it contains many stars and alot of dust and gases. Our milky way is a galaxy full of amazing stuff, many stars blow up and cause auroras in the sky. If you go to watch the aurora borealis(northern lights) , its amazing and beautiful. The sky turns green and blue and the stars appear.
0.75 km = (0.75×100000) cm = 75000 cm
