The inductance of a solenoid is given by:

where

is the vacuum permeability
N is the number of turns of the solenoid
A is the area of one loop of the solenoid
l is its length
For the solenoid in our problem, N=500, and the radius of one loop is r=0.025 m, so the area of one loop is

and its length is l=0.20 m
So the inductance of the solenoid is
Answer:
Vf=27m/s
Explanation:
Vf=Vi+at
Lets substitute the known variables into the equation:
Vf=15+10×1.2
Vf=27m/s
So itll be going 27metres per second
