A constant current of magnitude 16A
passing through a metal wire of diameter
face
1.6mm
, free electron density mật
in the string
22 3 10 cm
. Calculate speed
directional movement of the
free electrons.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
