1)a.A grind stone of 0.1m thick,1m of diameter and a relative density of 2.53 find-moment of inertia+ radius of gyration.
b)A gun is fired at a target 12km away at an angle of 35deg and hits target.How long is the projectile in the air and what's it's velocity?
need complete step by step answer,thanks..
