Q A jet is moving up with an acceleration"a" in the upwards direction. At an instant the driver throws coinwhen the velocity of the jet is "v". what will be the velocity and acceleration of the coin just after the instant when it is dropped.
When the stone is dropped at that instant also the acceleration of the jet is "a" and the velocity is "v". lets take the two cases
1. if the jet is in the gravitational field of earth :
T he speed of the dropped stone is "v"and the acceleration is "g" as the coin leaves the contact of the jet it acquires the velocity of jet
but will act under the acceleration "g"
2 If it is outside the gravitational field of earth:
it will acquire the velocity "v" and will proceed with the same velocity for the same reason as above
the coin will go some what up and it begins to fall....... it will be like a body that is projected from ground with some initial velocity........
