A battle ship (4.09*107 kg) fires a salvo of 3 rounds from its foward turret in the direction of the bow at an angle of 10 degrees above the horizontal. Each projectile weighs 1220 kg, each barrel is 20.9 m long and the muzzle velocity (I don't know whether this is initial or final velocity) of the projectile is 770 m/sec.

What is the acceleration of each projectile in the barrel and how long does it take to travel down the barrel?

2. Relevant equations

Vf=Vi + a(T)

S= Vi(T) + 1/2(a)(T)^2

a= vf-vi/T

3. The attempt at a solution

no clue!!
