.........Nucler fission.... .
NOTE: The strength of an electromagnet is directly proportional to not only the current but the number of windings. Doubling the number of windings doubles the strength of the magnet.

Answer:
3.48 seconds
Explanation:
At maximum height Vf=0 m/s
Vf= Vi - g*t
⇒g*t= Vi
⇒t= Vi/g
⇒t= 112/32.17 sec
⇒ t= 3.48 s
so the projectile will achieve its maximum height in 3.48 seconds.
