But, accelerations don't change between inertial frames. I'm confused with this.
Imagine a situation, 2 trains are approaching on a single track. And you are there beside the track in your car, moving with velocity 20m/s.
Now the train coming from your front will appear to have 20 + 20 =...
velocity of the bolt going up with rocket after t sec, v_{up} = at_{up} (up positive)
initial velocity is zero here as the rocket starts from rest.
Now this velocity becomes the initial velocity of the bolt when it starts to fall down.
When the bolt is falling, it is acted upon by -g...
Homework Statement
2 trains approach each other on same track with equal speed of 20 m/s. When they are 2km apart, they see each other and deaccelerate. If deaccelerations are uniform, how large the acc. would be to avoid collision.

From http://en.wikipedia.org/wiki/Electrolytic_capacitor"
"This is necessary because a reverse-bias voltage above 1 to 1.5 V[1][2][3] will destroy the center layer of dielectric material via electrochemical reduction (see redox reactions). Without the dielectric material the capacitor will...
