A projectile with a diameter of 100 mm moves in the gun

Projectile 100 mm gun barrel moves in 3 m long. The speed of the projectile out of the barrel when flying is 800 m / s. To stabilize the projectile in flight motion impart rotational movement by means of special helical grooves in the barrel. During movement in the trunk of a shell makes 1.5 turns. Determine the tangential and normal acceleration of a point lying on the side of the projectile at the time of his departure from the instrument.
